1. a small, hairless, beastly creature reminiscent of a cave troll.
2. A tiny cave dwelling creature that subsists on feces and cheap beer. The camenisch has been known to be very flatulent. The stench of a camenisch has been known to make maggots regurgitate. Always use caution when in the proximity of a camenisch. Studies have shown that people spending too much time near a camenisch usually end up vomiting and/or committing suicide.
3. A feeble minded and utterly annoying person.
I just saw a camenisch. Well, actually I smelled him before I saw him. Then I threw up.
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!!!
