lump knuckle

similar to a moose knuckle, but on a one-testicled man. To refer to a man who is squashing his one nut down one side of his overly-tight pants.

Glad to see Lance is back in the racing game. I have missed that lump knuckle.

Web Knuckles

While "nexting" through Chat Roulette, only to find your social partner to have his webcam pointed directly at the outside of his fist .... that is pleasuring his junk. Web Knuckles.

I was hitting next ... and then BAM ... got hit in the face with a screen full of Web Knuckles.
