What Are Idioms for Fun?
Idioms for fun are set phrases that describe enjoyment, play or celebration in a figurative way, not a literal one.
Oxford Learner’s Dictionary describes fun as the feeling of enjoying yourself, plus the activities you like. Idioms add color to that feeling. A plain “we had fun” turns into “we had a blast.”
These phrases fall into five moods: big happy fun, wild nights out, relaxing, small everyday joys, and playful or sarcastic fun. Learning them by mood is easier than memorizing one long list, because you can pick the right phrase in seconds.
Idioms for Big, Happy Fun
Have a blast, have a ball, have the time of your life and have a whale of a time all describe enjoying something a great deal.
Have a blast means to enjoy something very much. It sounds casual and friendly, so it fits stories about trips, parties and games.
“The team had a blast at the company picnic.”
Have a ball points to full, open enjoyment. It works well when you describe an event where everyone joined in.
“The kids had a ball at the school fair.”
Have the time of your life is the strongest of the group. It suggests the best time you have ever had, and speakers often exaggerate on purpose.
“I had the time of my life on that road trip.”
Have a whale of a time describes a hugely enjoyable stretch of time. No documented origin turned up for this phrase, so none is claimed here.
“Grandpa had a whale of a time at the family barbecue.”
Like a kid in a candy store describes someone thrilled by something they love. It adds a picture of childlike excitement.
“My brother was like a kid in a candy store at the electronics fair.”
Idioms for a Wild Night Out
Paint the town red, live it up and kick up your heels all describe going out and celebrating in an energetic way.
Paint the Town Red
Meaning: To go out and celebrate in a wild, lively way.
Origin (disputed): Phrase Finder reports that the phrase first appears in print in 1883, in The New York Times. A popular story points to 1837, when the Marquis of Waterford and his friends reportedly painted buildings red in Melton Mowbray, England.
That event is documented, but the phrase doesn’t show up in print for about fifty years afterward. For that reason, the link between the two is plausible but unproven.
Other theories involve red-light districts and “paint” as slang for drink. Phrase Finder judges a US origin around 1883 likely, and it calls the phrase somewhat old-fashioned today.
Example: “We passed our exams, so tonight we’re going to paint the town red.”
Live It Up and Kick Up Your Heels
Live it up means to enjoy life in a lavish way, often by spending freely.
“On holiday, we lived it up at a fancy resort.”
Kick up your heels describes lively enjoyment, often dancing or moving around.
“After the final bell, the class kicked up their heels at the dance.”
Idioms for Relaxing and Letting Go
Let your hair down and blow off steam both describe relaxing, but the first is about freedom and the second is about releasing stress.
Let Your Hair Down
Meaning: To relax, drop formality and act freely.
Origin (documented story): Phrase Finder lists the phrase as British and dates it to the 17th century. Women normally pinned their hair up, then let it down for brushing or washing.
Some websites add a story about towering hairstyles. That detail comes with no source, so treat it with care.
Examples:
- “After the big launch, the whole office let their hair down at karaoke.”
- “At my cousin’s wedding, even Dad let his hair down and danced.”
Blow Off Steam
Blow off steam means to release stress through fun, play or exercise. The phrase suits the end of a hard week.
“I play football on Fridays to blow off steam.”
Blow away the cobwebs works in a similar way. It describes clearing your head with fresh air or an enjoyable activity.
“After studying all day, we walked on the beach to blow away the cobwebs.”
Idioms for Small, Everyday Joys
Get a kick out of, just for kicks, make someone’s day, feast your eyes and with bells on describe small moments of enjoyment you meet in ordinary life.
Get a kick out of something means it brings you excitement or happiness.
“She gets a kick out of solving crossword puzzles on the bus.”
Just for kicks describes doing something only for enjoyment, with no other reason.
“He learned the guitar just for kicks.”
Make someone’s day means to make a person’s day happy. It fits kind gestures and good surprises.
“A thank-you note from a customer made my day.”
Feast your eyes on something means to enjoy looking at it, often for a long time.
“Feast your eyes on this view from the mountain top.”
With bells on shows you are excited and keen to join something.
“Are you coming to the party? I’ll be there with bells on.”
Monkey around means to fool around and have fun without being productive.
“The kids monkeyed around in the garden instead of doing homework.”
Playful and Sarcastic Fun Idioms
All fun and games, a barrel of laughs and like fun often carry a wink, because speakers use them to joke, warn or say no.
All fun and games describes something enjoyable and not serious. People often add “until” to warn that fun can turn risky.
“Jumping on the sofa is all fun and games until someone hits the lamp.”
A barrel of laughs means very entertaining, yet speakers often use it with irony about something dull.
“The three-hour safety talk was a real barrel of laughs.”
More fun than a barrel of monkeys pushes the idea further. It describes something extremely enjoyable.
“The waterslide park was more fun than a barrel of monkeys.”
Like fun is a sarcastic reply that means “certainly not.”
“You finished the report in an hour? Like fun you did!”
Time flies when you’re having fun says that time feels short when you enjoy yourself. People say it when a good day ends too soon.
“Is it midnight already? Time flies when you’re having fun.”

- Texting a friend: “We had a blast” or “I had the time of my life” feel natural.
- Talking about a team event: “The team let their hair down” sounds warm and friendly.
- Writing a formal email: use plain words like “we enjoyed the event.” Idioms such as “paint the town red” may sound too casual or dated.
- Joking with family: “all fun and games until…” or “a barrel of laughs” add humor.
- Answering a doubtful claim: “like fun” works only when you mean it as a sarcastic no.
Common Mistakes with Fun Idioms
Learners most often mix up fun and funny, drop small words, or pick a phrase that is too wild for the setting.
- “The party was funny.” Use fun for something enjoyable and funny for something that makes you laugh.
- Mixing up “have fun” and “make fun of.” The second means to mock someone, not to enjoy yourself. Oxford Learner’s lists “poke fun at” as saying unkind things to make others laugh.
- Dropping small words. Say “the time of my life,” not “time of my life,” and “a whale of a time,” not “a whale time.”
- “Paint the town in red.” The correct form is “paint the town red.”
- Using party idioms in formal writing. Phrase Finder calls “paint the town red” rather old-fashioned, and “have a blast” is casual.
- Hearing “all fun and games” as only positive. It often leads into a warning.
