the anal version of a queef. not just a fart but air and jiz combining to make a ploof noise when a cock is pulled out of ones ass
darren got embarrassed when he ploof'd after john pulled his dick outta his ass
when emo kids and crusty punks where their pants so tight it looks like they have a deformed camel toe
nice man toe trevor, thats cool your lil sister let you borrow her pants
