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.

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 it from behind while she tugged on her flap knuckle.
I could tell from the wet spot on her panties that her flap knuckle was ready for a flicking.
