Brooklyn Bootyslapper
The Brooklyn Bootyslapper is when a group of people, most likely people from Brooklyn, play a game of soggy biscuit and the one to finish last has to eat the biscuit and pull their pants down to reveal their bare ass. All other participants line up and give that ass the hardest wallop they can muster. This continues until the bootyslappee chickens out.
