Violent diarrhea. Most commonly found on public rest room walls, floors, or on the back of toilets. Also known as “AMD” or “Almost Made it Diarrhea” it occurs when a person with diarrhea is in dire need of a rest room and almost makes it to the toilet bowl, but ends up shitting all over everything else in the stall.
Did you clean the mens room? Hell no! Someone had blast all over the place in there.
