Knuckle Dip 

An accidental action that occurs when butt wiping. Usually occurs when one unknowingly has clogged the toilet, wipes his arse, and accidentally touches the water with one's knuckles.

I didn't know the toilet got clogged after my courtesy flush, so when I wiped my ass, I did a knuckle dip.
