buttgeist 

From the English "buttocks" and Germanic "geist" = ghost.

The haunting, stretched, sort of thin, really, feeling your wife's ass has after you cum in it (magnificently) and pull out.

Sweating, back arched, face flushed, Shana felt the metallic emptiness of the buttgeist as Jack pulled out of her ass.

Buttwings 

Buttwings are small wings that can be found on the rear-end (butt) of something; they are generally found on non-existent things like Victini and anything that's free to buy.

Victini has a pretty prominent, but small pair of Buttwings that allow it to fly around and cheat the laws of physics.
