[Diarrhea Roulette]
The act of walking around nervous that an unsuspectingfart may be the one loaded with a diarrhea bullet. Not to be confused with a shart, this is a full blast of watery shit that will ruin undergarments.
"I ate 20 hot wings last night and drank shitty beer." "I walked around playing diarrhea roulette all day, until the chamber had one in it." "I had to throw the underwear out!"
