While having sex you finger the girls ass and make sure to get her poo on your finger. When ready, you pull out (before during or after cumming as it does not matter.) and smear her poo from one cheek, across her lips to the other cheek. When she gets mad at you, simply ask "Why So Serious?"
Bob: Hey did you fuck anyone last night?
Stan: Yeah bro, I hooked up with this one chick. Idk her name, but it didnt matter when I did the poop smearing
Ruler of Lake Titicaca. Rumored to have a bunghole that gets very angry if it does not receive toilet paper. Cornholio the Great is often seen walking around with his shirt over his head and his hands in the air, chanting songs about his power, and his bunghole.
"I am Cornholio! You do not want to face the wrath of my bunghole, for I need TP!"
Butthead: Shut up, Beavis! (uh huh huh huh)
Beavis: Um, okay. (heh heh heh heh).
