one upmanshit 

A phenomenon that occasionally occurs in social gatherings that devolve into a nostalgia-fest conversation about fecal incidents such as soiling underwear, quality bowel movement and/or alcohol fueled defecating incidents. Inevitably, the conversation becomes a string of awful fish-stories about large bowel movements and creative placement and/or uses of them. The conversation becomes more and more repugnant at a exponential pace. Ultimately, the least attractive person of the coversation wins with the most horrifically grotesque story about his or her colon meat.

"...Last week, at Joe's bachelor party, Eric told us this story about crapping his pants on the way home from work that week. For some reason, the stripper decided she should become part of the conversation and told a story about how she once deuced through her g-string thereby cutting the turd in two. Eric rebutted by regaling us with a tale of a boat trip where he made some starboard diarrhea or something like that. That touched off about an hour of one upmanshit where each had one less appetizing story after the next...."
