Banana cream pie

Someone who isn't mentally stable, this can range from being "not completely there" to "bat shit crazy", but they are so attractive, people tend to overlook it in the hope that they will have sex with them.

A situation where a man or woman is willing to overlook the fact that someone they're with is mentally unstable, because they want to have sex with them.

This term is inspired by a bit that Katt Williams does in his 2008 stand up comedy special "It's pimpin' pimpin' " where he talks about how men will have sex with crazy girls, and when they yell out random stuff like "banana cream pie!!!"

when a man is having anal sex with a man or woman (usually man); he finishes in his/her butthole. later when the receiver poops, a dollop of cum garnishes the tip of the loaf

Well the Banana is a penis and the cream pie is cum in pussy.

Getting fucked in the ass with a ripe banana and having it break open inside your asshole. Leaving behind some creamed banana

When having anal sex, you slap them in the face, cum in their ear and mix it with the wax hence creating banana cream pie. then you take a dump in their mouth, forcing them to eat the before mentioned "banana cream pie"
