The act of being made, through no fault of one's own, the third wheel. Usually committed by a couple, especially a Couple Monster, the individual being scheißmeistered is then left in a moment similar to an awkward turtle.

"Whoa, look at Claire- she is getting COMPLETELY scheißmeistered. Look at the stain she's making in her unterhosen!"
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!"
