Well, what do you call it?

In an effort to have a little humor and be more creatively interesting here, I'm asking the question, about something everyone has in common; leaving that something special behind in the toilet - what do you call it?

BM, (Bowel Movement), excrement, waste, a relief, poo poo, stinky, log, a dump, pinch a loaf, turtle's head, crap, shit...
