Poop Knuckle

the result of an improper angle of approach when wiping your -ss from a particularly messy p–p-session. p–p 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 -ss. this often resulted in a nasty case of p–p knuckle.
the second knuckle in (heading towards the hand). originating from the knuckle at which you stop at when inserting a digit into another’s -sshole.
used to warm up/stretch out an -sshole before -n-l s-x.
i was playing ping-pong and the ball hit off my p–p-knuckle.
when wiping the -ss after an exceptionally productive p–p, 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 d-mned p–p knuckles.
a place on a p–p where it is thicker than elsewhere on the p–p.
sorry i took so long in the can; i got stuck on a p–p knuckle and it took a while to force it out.
the point to which p–p comes up the shaft of the p-n-s after having -n-l s-x with someone who didnt “clear themselves” before hand.
d-mnit carl, you forgot again?! this p–p knuckle has to be at least four inches…this time your cleaning it.
