A bonerdoner is a guy that a girl, usually very attractive, elects to have pre-arranged sex with her one or more times just to get over a relationship/bad test/daddy problems or just because she is extremely horny at the moment. A bonerdoner differentiates from a fuckbuddy in that they do not necessarily have to be friends, nor do they have to have sex more than one time.
Julia: So, did you get a bonerdoner for the big weekend?
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).
