Michigan Kurplunk
When someone takes a shit in the toilet, and without flushing, pick your partner up by the legs and drop her in headfirst . Just before she drowns in your shit, flush the toilet and clean her off with toilet paper.
Girl's friend: "Is that corn in your nose?"
Girl: "Yeah my boyfriend gave me a Michigan Kurplunk while we were in Detroit."
