Similar to a creampie but this time it comes out the ass.
After anal sex, and not a quickie either, you splooge inside a chicks ass and when you pull out, brown coloured cum oozes out is your butt butter. Not to be considered in the pornstar biz (as they are clean hooped normally) but usually amateurs with unwiped/non-enima cleaned poopshoots.
