A contest in which roommates do not flush the toilet after defecating such that the feces piles up in a manner similar to the building of the tower in the game of jenga. The loser is the one who either gives in first and flushes the toilet or resorts to doing his or her business outside.
Bill and Tommy played a game of bathroom jenga that lasted for three weeks. It ended in a draw when DHS was called and the house was condemned.
