when someone farts, and the smell of it smells like a mix of blood piss and jizz. this usually happens after anal sex in both men and women. More commonly used in messaging as ABJPF.
One who loves to be sodomized (preferably by frat brothers). As a result, when they flatulate soon after the sodomy occurs (it occurs often i'm sure) they fart jizz. The jizz comes out in a brownish hue because it has been residing in ones colon.
