Dingleberry Plow
When a girl (or a guy) misses a peice of shit when wiping, wait at least an hour for it to dry then use your cock or a strap-on to pack that bastard back where it came from.
Lisa had a nasty ball of shit hanging from her asshair, so I bent her over a chair and gave her the dingleberry plow. That'll teach her to be thorough.
