The disgusting yet wickedly funny act of wiping your ass and then tossing the poo smeared wad of toilet tissueover the top of the stall and onto someone using the urinal in front of you.
when you have to dookie really bad, and you hold it and hold it, and your running (pun intended) into the bathroom, and you sit down, and the dookie shoots from you like a bazooka, with out a second to spare, and you think "wow, that was a dookiebazookie"
