Most languages use distinctive expressions to make conversations more lively and fun. These idioms paint funny mental pictures that connect silly visuals with real-life situations. They help us express our feelings, mostly of frustration, scepticism, and disbelief. These funny English sayings focus on the silliness of life by being silly themselves.

Let's go

A Few Sandwiches Short of a Picnic

Meaning:
Someone is not very intelligent or is a bit odd.
When to use:
Use this in a light, humorous way to describe someone acting silly or lacking common sense.
Example:
"He wore sunglasses indoors at night, he’s a few sandwiches short of a picnic."

Imagine inviting a crowd to a picnic where there isn't enough food for everyone. One would have to be crazy to host such an event, right? A picture of craziness is, in fact, this idiom's purpose. If someone is a few sandwiches short of a picnic, they lack common sense and intelligence. You can describe such a person with other fun idioms that mean the same thing:

  • a few cards short of a deck
  • a few beers short of a six-pack
  • a few bricks short of a load
  • a few points short of promotion

All Bark and No Bite

Meaning:
Someone who makes threats or boasts but doesn’t follow through.
When to use:
Use this when describing a person who talks tough but doesn’t take action.
Example:
"Don’t worry about him, he’s all bark and no bite."

Barking dogs don't bite.

Folk wisdom

This 'wisdom' comes from the thought that dogs bark to warn people away; biting dogs don't warn you before sinking their teeth into your leg. It's not true that barking dogs don't bite, of course; plenty of dogs bark before biting. Still, this 'wisdom' is the root for this funny English idiom.

"Ah, don't mind him. He's all bark and no bite" means a person might say mean things or speak in a rough manner, but they're harmless. It's a good phrase to hear when you meet someone you're not sure about. "You're all bark and no bite!" is also a great way to tease a bully.

Between a Rock and a Hard Place

Meaning:
Facing two difficult choices with no easy solution.
When to use:
Use this when someone must choose between equally unpleasant options.
Example:
"I’m between a rock and a hard place, either I stay in a job I hate or quit without a backup."

The mental picture this idiom draws is absurd, because rocks are hard, too. When you say you're caught between a rock and a hard place, you're communicating that you're stuck in an impossible situation. Any choice you make will have severe consequences. Imagine being in such a place as the singer above, or in one of these:

🙋‍Question: "Are you really going to quit your job?"
🔊Answer: "I don't know. I'm between a rock and a hard place right now. I hate the work and don't earn enough, but nobody's hiring, either."
🙋‍Question: "Whose side are you taking, Dad's or Mum's?"
🔊Answer: "Don't put me between a rock and a hard place! They need to work things out on their own!"

By the Skin of Your Teeth

Meaning:
Barely succeeding or narrowly escaping failure.
When to use:
Use this when something is achieved at the last possible moment.
Example:
"I passed the exam by the skin of my teeth."

Imagine how horrifying skin-covered teeth would look! Imagine having to care for such a set of teeth, including making sure they don't bleed every time you eat. Aren't we lucky our teeth have no skin covering them?

Luck (and not losing any skin) defines this idiom. "I passed my exam by the skin of my teeth" means luck was heavily involved in your exam results. 'Barely' is another one of its definitions. You can squeak out of any trouble by the skin of your teeth, which means you barely made it through a bad situation.

Cash Cow

Meaning:
A reliable source of steady income or profit.
When to use:
Use this in business contexts to describe something that consistently makes money.
Example:
"That product has become the company’s main cash cow."

Cows are wonderful, docile beasts that have served humanity since the dawn of civilisation. They've been our food and drink, our help in the fields, and a source of material for sturdy shoes and clothing. And, since the 1960s, they've been our bank machines.

What is a cash cow?

Peter Drucker, a management guru, coined the term 'cash cow' to mean a product or business with high market value that helps the company earn a lot of money.

The 'cash cow' idiom is especially popular in Business English environments but many others use it too. 'Cash cow' can describe anything that delivers lots of benefits. "My gran's my cash cow. She gives me all the food I want and some spending money, besides."

Everything But the Kitchen Sink

Meaning:
Including almost everything possible.
When to use:
Use this to describe something overloaded with many items or details.
Example:
"She packed everything but the kitchen sink for the weekend trip."

In many English-speaking countries, moving house means packing up everything; only the walls and fixtures (lights and plumbing) stay behind. That includes the kitchen sink, of course. From this, we can understand that this idiom means 'absolutely everything', even the most unimportant stuff. Try these sample sentences:

She carries everything but the kitchen sink in that big purse!
I got robbed last night; they took everything but the kitchen sink!
Stop asking for stuff; I already gave you everything but the kitchen sink!

In Hot Water

Meaning:
In trouble or facing consequences.
When to use:
Use this when someone has done something wrong and may be punished.
Example:
"He’s in hot water after missing the deadline."

This is one of the least funny idioms on our list, thanks to its dark history. During the Middle Ages, people accused of crimes or witchcraft were forced to put their arms in boiling water. If the burn healed, it meant you were innocent because God intervened and healed you.

Still today, being in hot water means being in trouble though, fortunately, nobody gets boiled alive anymore. Have you ever told your friends you have to be home by dark or you'll be in trouble? Next time, say it like this: "I'm going to be in hot water if I don't get home by dark!"

A man wearing a striped shirt holds his head in his hand in front of a computer.
This person appears to be in hot water!

It's Not Rocket Science

Meaning:
Something is not complicated or difficult to understand.
When to use:
Use this to emphasise that a task is simple.
Example:
"Just follow the instructions, it’s not rocket science."

Rocket science ranks among the most complex, intellectual disciplines. The opposite of rocket science is simplicity; something that doesn't need a lot of thought. When you tell someone, "It's not rocket science!", you're saying whatever they're trying to do is easy. The related idiom, 'It's not brain surgery', means the same thing.

  • I don't know how to ride a bike.
  • I'll never understand trigonometry!
  • Can you cook spaghetti?
  • How can people just climb mountains?
  • Well, it's not rocket science!
  • Geez, it's not brain surgery!
  • Sure, it's not rocket science.
  • Well, it's not brain surgery.

Lost Your Marbles

Meaning:
Gone crazy or behaving irrationally.
When to use:
Use this when someone is acting strangely or illogically.
Example:
"Have you lost your marbles? That idea makes no sense!"

If your friend suddenly suggests doing something wild and dangerous, you should try to stop them. Shouting "Have you lost your marbles?" is a fun and effective way to do so. Losing one's marbles means the same thing as losing one's good sense.

Let's go

Off Your Rocker

Meaning:
Crazy or not thinking clearly.
When to use:
Use this informally to question someone’s sanity or judgment.
Example:
"You want to swim in that cold water? You’re off your rocker!"

By contrast, being off your rocker is a more general expression of craziness. "You're off your rocker if you think I'm going to do that!" means you have no hope that that person will ever recover their good sense.

compare_arrows
A mild difference

Losing one's marbles is generally temporary.
Being off one's rocker is a permanent condition.

On the Same Page

Meaning:
In agreement or sharing the same understanding.
When to use:
Use this in teamwork or discussions to confirm alignment.
Example:
"Let’s make sure we’re on the same page before moving forward."

This idiom ranks among the most common phrases; it means "We're thinking the same thing; we agree." English speakers use it in work situations: "Just so we're on the same page, go over the plan again" and in therapy settings: "Let me get on the same page with you." Friends, families, and social groups use it, too: "Let's get on the same page. Are we going hiking this weekend or not?"

Out of the Blue

Meaning:
Happening unexpectedly or without warning.
When to use:
Use this when something surprising occurs.
Example:
"She called me out of the blue after years of silence."

Have you ever seen lightning from a clear blue sky - the origin of this idiom? It's shocking, surprising, and completely unexpected; exactly what this phrase means. You can use it to express your emotion about something that happened that you did not plan on, as the Friends clip above demonstrates.

"And then, it came to me, out of the blue!" = I suddenly had this great idea.
"And then, out of the blue, she hit me!" = you weren't expecting to get hit.
"Did you know he would ask you out?" "No, it was totally out of the blue!"

Pig Out

Meaning:
To eat a large amount of food quickly.
When to use:
Use this casually when talking about overeating.
Example:
"We pigged out on pizza during the movie."

Humans have a close bond with animals, so it's no surprise that the English language has so many idioms featuring animals. This particular idiom does not paint a pretty picture, though. Imagine a grunting pig, nose in its food and smacking its lips. "Pigging out" means exactly that: eating a lot, with no decent manners, just like a pig.

Cultural considerations

English-speaking cultures believe pigs are fat, dirty, lazy, and stupid animals.
Any English idiom involving pigs tends to paint negative pictures.
"When pigs fly" is a good example. How can a fat, lazy pig fly?

The Pot Calling the Kettle Black

Meaning:
Criticising someone for a fault you also have.
When to use:
Use this when pointing out hypocrisy.
Example:
"You’re late again? That’s the pot calling the kettle black!"

The joke here is that both the pot and the kettle are black.

This idiom paints a picture of the times when people cooked over an open fire. The fire's smoke turned everything black. If you know someone who's a pretender, a fraud - a hypocrite, this is the perfect answer to any claim they make.

Let's say your workmate loves to eat sweets. One day, they see you eating a pastry and 'make a joke' about how you're going to get fat.

You should say, "Well, there's the pot calling the kettle black!"

Pulling Someone's Leg

Meaning:
Teasing or joking with someone.
When to use:
Use this to clarify that you’re joking or not serious.
Example:
"Relax, I’m just pulling your leg!"

Like other idioms on this list, this one has a dark history that traces back to London's pickpocket days. The thieves worked in teams; one (a child) would distract a passerby by pulling on their trousers to get their attention while the other slipped their fingers into the passerby's pockets.

The best scam response

Scam message: "You owe the tax office (a sum of money). Pay securely by tapping this link."
Your response: "Don't pull my leg, mate! You're not the first 'tax office' to send me this message."

Put a Sock in It

Meaning:
Be quiet or stop talking.
When to use:
Use this informally when you want someone to stop speaking.
Example:
"Can you put a sock in it? I’m trying to concentrate."

It seems like the longer this list goes, the more terrifying these idioms become! 'Putting a sock in it' is what a kidnapper does to their victims to keep them quiet: they stuff a sock in their mouths. Luckily, you don't have to actually stuff a sock in someone's mouth. You can tell them to shut up with this idiom.

Oh, put a sock in it, will you? I can't hear myself think!

Read Between the Lines

Meaning:
Understand a hidden or implied meaning.
When to use:
Use this when something isn’t stated directly but can be inferred.
Example:
"If you read between the lines, you’ll see she’s not happy with the decision."

As an English student, you surely know that a lot of this language gets its meaning from context. Would you be surprised that situations also get their meaning from context? That's exactly what this idiom means.

'Reading between the lines' means understanding a situation not just because of the words used to describe it, but also because of other aspects. "Did she really say she likes you?" "No, but I can read between the lines. Her eyes were begging me to ask her out!"

Take a Load Off

Meaning:
Relax or sit down and rest.
When to use:
Use this when inviting someone to relax.
Example:
"Come in and take a load off after your long day."

The human body is an engineering marvel; how do our feet not crumble under the weight of our whole body? That's one meaning behind 'take a load off', which means 'sit down'. It can also mean 'don't let your troubles burden you', as Ariana suggests we all do. Do these sample sentences fit in your life?

"You can carry on shopping. I'm going to take a load off right here, on this bench."

"You're looking troubled, dear. Wanna tell me about it? Go ahead, take a load off."

Take a load off, don’t take everything so seriously.

Two Left Feet

Meaning:
Being clumsy, especially when dancing.
When to use:
Use this to describe someone with poor coordination.
Example:
"I’d join you on the dance floor, but I have two left feet."

Of all the idioms on this list, 'two left feet' has the most interesting history.

It used to be a compliment given to talented ballerinas because ballet dancers always lead with their left foot. If you had two left feet, you must be unusually talented!

Over time, social dancing became more popular and the idiom's meaning changed.

Now, it means a clumsy, uncoordinated person. It still relates to dancing: "With my two left feet, I'm no good at dancing."

But you can also describe someone who always trips over their own feet: "Don't walk too close to him; he'll bash into you with his two left feet."

Use Your Loaf

Meaning:
Use your brain or think carefully.
When to use:
Use this informally to encourage someone to think.
Example:
"Come on, use your loaf, you know the answer!"

We end our list with a typically British idiom, which is also a common idiom about food. 'Use your loaf' means 'use your head' or, more specifically, your brain. It mirrors the slang used in American English: 'use your noodle'. You can use them when you want someone to think of a solution themselves.

How am I gonna figure that out?

How am I supposed to do that?

By using your noodle, like the rest of us do.

Use your loaf! Don't count on me to do your thinking.
