It came up in another thread, but to avoid derailing it, I figured we could get a fun little collection here.

Two from my native language roughly translates to:
"Having your beard stuck in the mailbox."

"Taken a ♥♥♥♥ in the blue cupboard."

[Wolverine]

"Insulted liverwurst."
"Not spider."
"I can't eat as much as I want to puke."
"Louse ran over the liver."
"Had a pig."

[Brownies]

Well, in french you have so many funny expressions but here are two:

"Il ne faut pas pousser mémé dans les orties"
which translate to: You must not push grandma into the nettles
-> It means 'you are exaggerating'

"Pisser dans un violon"
which translate to: To piss in a violin
-> It means doing something useless or wasting time

[Pippzu]

"Dear child has many names - but so does ugly child"
