Punishment for intentionally breaking a rule in a drinking game. For example if during a game of kings someone needs to use a bathroom but doesn't have a toilet card, they can do so, on the condition that when they get back they receive a cuban abortion.
The procedure for the operation is that the victim stands up and schols (chugs) a beer at which time someone else will get to punch them in the stomach.
Usually results in someone winded and throwing up, but they'll be alright in a few minutes.
It was so bad, I really had to take a leak so I had to get a cubanabortion. Through up all over the back garden.
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).
