Knuckle Cluster

When you're in bed with your man and he lodges his entire fist into your cooch. he then squirms his hand around until he sees his knuckles through your belly. Once seen they instantly cum.

Ronald: Did you hear? Samantha got knuckle clustered by David
Arnold: Really?
Ronald: Yeah. She died mid-way and he sat there cumming. He soiled the bed sheets completely white
Arnold: Damn. It was good when I railed her ya'know?

knuckle hamburger

A variation of a hand job. The fist is applied to the penis, flattening it against the body.

This action mimics the flattening of ground beef into a hamburger patty, thus the name.

Dude 1: I heard she gives a wild knuckle hamburger.

Dude 2: Yeah bro my dick was as flat as a Steak n Shake burger!
