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.

I'm not going in there until you scrape that butt butter off.

Like peanut butter, it sticks to the upper palate of your mouth.
I was eating this chick's ass, she clipped out some butt butter and my tongue stuck to the roof of my mouth. I was looking for a glass of milk to wash it down.
