When a white girl and a person of color(or the other way around) have anal intercourse.

Comes from the Reese's Peanut Buttercup commercials. "Your chocolate is in my peanut butter. No your peanut butter is in my chocolate."
I was hooking up with Angela when she asked me if I wanted to Peanut Buttercup.

When a guy takes his dick and sticks it into jar or peanut butter puts the peanut butter back into the cupboard. Then sticks his dick in the girls pooper. Then the girl licks off everything!
"hey baby want to do the peanut butter cup tonight"
"you know how hard that would be to get the peanut butter out of my ass"
