1. A game played in men's public restrooms while dropping a deuce.
The rules: Nugget must make a splash which in turn allows you to yell, "THUNDERDUUUUUUUNK!" If audible from outside the restroom you score one point.
If turd audible you earn two points.
Play until fifteen points scored.
A dude runs into the men's and crashes into the stall and lets out a deuce and it is a splasher so he shouts, "THUNDERDUUUUUUUUUUUUUUUUUNK!"

Man 1: "Dude I totally just heard you thunderdunk out here!"
Man 2: "Yeah that thunderdunk just ripped my O ring!"
