Flap Knuckle

An extremely engorged clitoris quivering on an aroused state.

I was hitting it from behind while she tugged on her flap knuckle.

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.
