A neighbor representing two inches of tiny tantrum. The most he will ever use his third leg is jacking off to a pack mule eating oats. Also can be defined as one who symbolizes a true pussy.
Kyle crane stop being a three-legged twat sickle, and stop picking up BOFUBs. Quit getting sodomized by the imbred mule that lives in your basement. Talk to a decent looking girl you three-legged twat sickle.
