A poop crayon is a poop that is used to write on the walls of a narrow bathroom stall. This usually happens when some emergency occurs when the poop is part of the way out your bum- you stand up, bend down, move around and meanwhile your half-extruded poo is writing all over the walls.

Once I viewed the stall smeared with poo, I formed my poop-crayon theory.
