Definition

A classic, somewhat antiquated way of calling someone a wise-ass or generally annoying person who's being difficult for no good reason. It's the PG-rated insult your grandfather might use when he's trying to keep it clean at the dinner table. Less offensive than its anatomical cousin but somehow more condescending.

Example Usage

Don't be a horse's ass, just admit you were wrong about the directions.
