A casual slang term used to say goodbye to person. Ususally to a hot woman after she has shot a guy down in flames when trying to pick her up. A way for the guy to say goodbye and leave the option for her to come back for more of him. He's basically saying, I lost out no, but I'll knob you later (perhaps when she's a bit more drunk).
The term is catchy enough for guys to say to eachother in brohole kind of way.
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)
