From old-school insults to bizarre new expressions, here are 30 funny swear words that will have you cackling (and maybe even adopting a few of these expletives for daily use).
A Cheat Sheet of the Funniest Fake Swear Words
1. Thunder Nugget
Ever wanted to insult someone without them realizing it? “Thunder Nugget” is perfect for that! Imagine calling someone this instead of a regular insult. It sounds almost endearing—until they figure out you just called them a tiny storm-related disaster.
2. Son of a Biscuit
A classic among funny dirty words, this one lets you express frustration without crossing the line. Whether you stub your toe or spill your coffee, “Son of a Biscuit!” works wonders. It’s got the intensity of a real swear word—but with the innocence of breakfast.
3. Fartknocker
Straight out of the 90s, “Fartknocker” is one of the funniest cuss words that sounds way worse than it actually is. It’s the perfect word to call someone who’s being a little too annoying. Bonus points if they look utterly confused when you say it.
4. Craptacular
This creative curse word blends “crap” and “spectacular” into one glorious explosion of sarcasm. If you’ve ever had a moment when something is so terrible it’s almost impressive, this is the word for you. For example, here’s a quote: 'That movie was absolutely craptacular!'"
5. Cockwomble
A personal favorite from the UK, “cockwomble” is one of the most creative curses out there. It’s got a satisfying sound and just the right level of absurdity. Perfect for when someone cuts you off in traffic, and you want to sound classy while still insulting them.
6. Numpty
The Scottish gift to the world of swearing! A “numpty” is a fool, a dummy, a person who makes you question humanity. Among swear words, this one feels just right for friendly teasing. “You absolute numpty” is way more fun than just calling someone an idiot.
7. Dunderhead
This one comes straight from Shakespearean insults! “Dunderhead” sounds classy while still getting your point across. It’s the kind of insult a medieval knight might use before dueling someone.
8. Fiddlesticks!
A wholesome alternative to dropping the F-bomb, “fiddlesticks” is the ultimate funny bad word phrase when something goes wrong. It’s old-fashioned, ridiculous, and guaranteed to get a few laughs.
9. Clodhopper
A “clodhopper” is a clumsy person with big, awkward feet. If your friend keeps tripping over things, this insult is perfect. “Nice one, clodhopper!” is way better than just rolling your eyes.
10. Shabadoo
“Shabadoo” doesn’t even make sense but feels fantastic to say. Yell it when you drop something, miss a shot in a game, or just feel like causing confusion.
11. Gobbledegook
Ever heard someone talk absolute nonsense? Next time you’re stuck listening to someone blabber about something completely ridiculous, just shake your head and mutter, “That’s a load of gobbledegook.” A top-tier expletives option!
12. Nincompoop
This old-school insult is one of the best of all time. Calling someone a nincompoop is like saying, “You’re a fool,” but with extra style and flair.
13. Snollygoster
An insult with history! A “snollygoster” is a sneaky, selfish person who cares only about themselves. Perfect for shady politicians, cunning co-workers, or that one friend who always ‘forgets’ their wallet.
14. Bumfuzzle
If something confuses or baffles you, just say, “Well, that’s a load of bumfuzzle.” Not only does it make you sound fancy, but it also keeps things lighthearted when you’re genuinely lost. One of the best words to confuse everyone around you!
15. Lickspittle
Calling someone a suck-up is so overdone. Instead, call them a lickspittle — an old-fashioned insult for someone who shamelessly flatters people in power. It’s classy, weird, and hilariously savage.
16. Flibbertigibbet
Do you know someone who just won’t stop talking nonsense? A flibbertigibbet is a person who chatters endlessly about nothing important. A perfect insult for that friend who tells 20-minute stories with no point.
17. Fustilarian
Straight from Shakespeare’s insult vault, “fustilarian” is an elegant way to say “lazy good-for-nothing.” If someone is lounging around doing absolutely nothing productive, hit them with this phrase, and enjoy their confused reaction.
18. Malarkey
Need to call out someone’s nonsense? “That’s a bunch of malarkey!” is a perfect way to dismiss something ridiculous while still keeping it polite. A must-have in your collection!
19. Muppet
A British classic! Calling someone a “muppet” means they’re acting a bit dim-witted or silly. Simple, effective, and with a touch of British charm.
20. Twit
Short, simple, and incredibly satisfying. Calling someone a twit is like calling them an idiot, but in the most ridiculous way possible. Perfect for casual insults that won’t start an actual fight!
21. Wazzock
Another delightful British insult! A “wazzock” is a complete fool, and it rolls off the tongue beautifully. Use it when someone does something mind-bogglingly dumb.
22. Dingbat
If someone’s acting particularly clueless, “dingbat” is the perfect insult. It’s lighthearted, funny, and gets the point across without being too harsh.
23. Jiggery-Pokery
This phrase sounds absolutely ridiculous, which makes it all the more fun. It means trickery or deceit, so if you catch someone being sneaky, just say, “I don’t like this jiggery-pokery!” and watch their face twist in confusion.
24. Hootenanny
Not exactly a swear word, but this one is fun to yell when something crazy happens. “Well, this is turning into a real hootenanny!” works in nearly any chaotic situation.
