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!
