Poop Knuckle 

The result of an improper angle of approach when wiping your ass from a particularly messy poop-session. Poop gets on your knuckle. Usually occurs when you lift a cheek to the side and attempt a wipe.

Steve liked to lean to the left when he wiped his ass. This often resulted in a nasty case of poop knuckle.

Sorry I took so long in the can; I got stuck on a poop knuckle and it took a while to force it out.

When wiping the ass after an exceptionally productive poop, a knuckle is accidentally raked across the large, volcanic cone-shaped pile.

I must remember to give myself a courtesy flush to keep from getting these damned poop knuckles.

The second knuckle in (heading towards the hand). Originating from the knuckle at which you stop at when inserting a digit into another's asshole.
Used to warm up/stretch out an asshole before anal sex.

I was playing ping-pong and the ball hit off my poop-knuckle.
