The act of shitting in the shower, then stomping the shit through the shower drain/grate. There then is a rat that eats the shit in the sewer and finds its way to a diner, home, etc... The rat then dies in a potato bin from ingesting whatever nasty garbage you ate and shit out, gets mistaken for a potato, Gets fried and eaten by some fat little kid who looks like gibby from icarly.
