Knuckle Fuck

When hitting a large jump (booter) mainly on skis there is a roller or knuckle that the jump sits on. If you hit that jump and land a little short that is called a case. But if you case the jump so hard that you are ejected from your skis and you thrust your body so hard against the landing that is called a Knuckle Fuck because you are fucking the knuckle.

Dude, that guy hit the pro jump line and knuckle fucked the last jump.

Dick Knuckle

When your cock torques off to the left (or right), resembling a semi-ripe banana when erect, and a partially hooked finger when flaccid. Common in angry short men, orangutans, and intellectual pygmies.

"Dude, did you see Mike in the shower?"

"Yeah bro, what the actual fuck is up with his dick? It looks like a hooked finger"
"Total dick knuckle going on there. Fucking gross."

Gimme knuckles

Another way to say fist bump

Imagine 2 people playing Darts for the same team of 4 players. One team mate scores 180 points with 3 Darts (taking the game, because their team needed to score 180 points to win the game)

Player 1: Holy Crap, 180!!
Teammate: Dude, gimme knuckles!!!
The winning team's 4 members all bump fists.
