A penis which is similar to that of a weasel's, in that it is extremely pink, slimy, and unsheathed in a manner much like a dog's penis. However, weasel penises rarely reach lengths of greater than 2 1/2 inches.
"Fuck you, you son of a bitch!" yelled Derek's girlfriend when he tried to touch her with his disgusting weasel penis.
