Knuckler

(n) the extra-ordinarily thick end of a shit log that you have to force out before the rest can pass comfortably out of your sphincter.

Sean thought he was giving birth as he forced the knuckler out of his sphincter.

knuckler

In Ice Hockey, a puck that flutters through the air after being shot, often from a deflection, sometimes from being a rolling puck when it was shot. It was Russ Tyler's favorite shot in the Mighty Ducks movies.

Also known as a knuckle puck.

That goalie had no chance to anticipate where the puck would go, it was a knuckler.
It's Knuckle Puck time! - Russ Tyler

White Knuckler

When one has to shit so forcefully that it is required that one grips the top of the bathroom stall so tightly that your hands, and most notably your knuckles, turn white. Often accompanied by excessive groaning, tears,and, in truly tragic situations, blood. Happens when the body lacks water to a degree that your intestines are almost stopped up but can still be cleared with enough 'push'(not constipation, but just barely).

I assumed from all the grunting that the poor chap in the stall next to me is in for a white knuckler.

"Jesus Christ, you took a long time to shit" "Yeah, it was a white knuckler."

"That was my third white knuckler this week. I'm gonna have to start shotgunning prune juice before every meal or just start cutting cheese out of my diet."
