busted knuckle 

Ripped, torn, scarred, aching flesh on the hands as a result of mechanical work. Usually the result of a slipped wrench or a screw that comes loose more easily than expected.

When working in a tight space underneath your car without much room to move and you are trying to remove a hex nut, next thing you know your wrench slips with a metallic noise and you've smashed your hand into the body of the car resulting in a busted knuckle. And it hurts like a motherfucker.

Anaheim Knuckle-Buster 

To cum on your fist and punch someone in their face.

The Canadian Knuckle Buster

Ex. I was at the Hosher Hut last night and met an amazing women. She took me back to her place only to crack open some maple syrup and try The Canadian Knuckle Buster.

Goldsboro Knuckle Buster 

A take on a double shocker from eastern North Carolina.

The Goldsboro Knuckle Buster is essentially 4 in the stink and two in the pink.

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.
