One of santa's little helpers. He escaped from the Asylum up north. Now he hides in peoples behinds, usually in the rectum. If you detect an Ass elf early, you won't have to dig it out with plyers.
"If Jimmy left that Ass elf in for 2 more days, they would've had to rip him a new one just to get it out."
