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.
