Let's be bad

It's been a while since we had a bad word, so here we go, today "foutre" (pronounced footr), which has numerous interesting meanings:

• As a masculine noun, it is slang for sperm
• As an exclamation, it is very close to "fuck", e.g.:

foutre! = fuck!
j'en sais foutre rien! = I don't know fuck about it!
foutre non! = fuck no!

• As a verb, slang for to do

E.g. qu'est-ce qu'il fout? = what the hell is he doing ?
qu'est-ce que ça peut foutre? = what the hell does it matter ?

• As a verb, slang for to give (a blow, a kick...)

E.g. ça m'a foutu un coup = it was a real blow to me

• As a verb, slang for to put

où t'as foutu les clés? = what the hell have you done with the keys ?

• As a verb, can also simply mean to fuck

va ta faire foutre! = go to hell (literally go get fucked), pronounced vatfayrfootr

• Other miscelaneous expressions:

je lui ai foutu une claque = I slapped him
tu te fous de ma gueule? = are you making fun of me ? / kidding me ?
je m'en fous! = I don't give a shit
