A crapenis is a crappy penis, as described by another person after starting to hook up. This can mean it is too small, to skinny, too stinky, etc for the person to want to continue hooking up. It usually means the end of the hookup, unless the person hooking up with the crapenis in intoxicated or just really needs some D.
Girl, I went home with that cute guy last night but it turned out he had a crapenis. It was so small I could barely find it! I used my dog as an excuse to get outta there!!!
