Wiping an ass back to front with the result having shit smeared across the back side of the scrotum. People with this condition typically feel a crusty, foul smelling, and very uncomfortable sense of unease while presenting an extreme lack of personal hygiene. It can be devastating for the partner when participating in sexual intercourse. The only way to aviod is wiping the rectal region with 3ply toilet paper in a front to back manner.
My friend wiped his ass from back to front and ended up with poopie nuts.
