This is the person with whom you reunited, for whatever reason, after previously ending a relationship. He/She was your ex-boy/girlfriend and now is your y-boy/girlfriend. The term was created to facilitate communication. The homonym was appropriate for the reasons everyone asks.
“My y-boyfriend and I are going to his cousin’s wedding.” The listener can understand how that experience may be different than if you were a new, current, or just a friendly date. In general, the listener understands that you have had a relationship with this person, parted with them, grown, and reunited after working out your problems….or not, so some say, “Why?”
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)
