Bung hole

[Mark Zuckerberg]

Another term for asshole, derived from the hole that a bung (stopper for a hole in a barrel) fits in.

[Sonia]

The hole in the side of a wooden keg used to fill said keg with beer. The Bung Hole is then stopped shut with a bung and hammered in place with a bung hammer.
Despite its often misrepresented confusion with the Anus, bung hole is a perfectly useable word at state dinners with the governor...If you of course are in the study of fine spirits.

[Donald Trump]
