What is Ass Quief?
When two homosexual males are having butt sex and the guy taking it up the ass cuts a fart. Some people find it debateable whether or not it is a fart or a quief, so I'm just calling it an ass quief.
"Oh my gawd, so we were doing the nasty last night, and I was all putting it in Jeff's butt when he let out an enormous ass quief! Then I had to stop because I went limp."
