fartpuncher 

(slang, pejorative) A homosexual male. The term is generally used to refer to gay men who participate in anal sex. However, like most pejorative terms with homosexual nuance, heterosexual males often use it to jokingly mock one another.

Tom is such a fartpuncher! I caught him doing anal with Joe a dozen times last week!

fartmuncher 

One who sniffs and breathes in others farts in an attempt to get hi.

"You're so fat you can't get out the door!"

"At least I'm not a fartmuncher!"
