When a person has a violent and severely explosive bowel movement so much so that it resembles a digestive "exorcism" of foul smelling, rotting waste matter sent by Satan through the depths of your cursed colon. Like the "asspocalypse" this kind of bowel movement can trigger loss of consciousness, muscular spasms within the legs and may need supervision by the occasional priest.
