Knuckleduster

A double jointed reverse hand job.

Jim said his dick was bruised, because he got a knuckleduster from a circus freak show.

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.

When a woman has a camel toe on display that’s quite larger than most moose knuckles displayed by men.

“Yo bro think I’m gonna hookup with Cindy tonight”
“Cool your jets bro, I saw her the other day displaying a serious knuckletoe.”

Knuckle buster

While in spoon position with your partner, you put your pinky in the Booty hole, ring and middle fingers in the vagina, and use your pointer finger to stimulate the clitoris.

Whether my wife is being naughty or nice, I always end the night with a knuckle buster.
