spherical asshole

A complete asshole. An utter waste of chromosomes. Spherical because a complete asshole has no redeeming features whatsoever and is still an asshole no matter which way you look at him/her, just as a sphere presents the same circular outline no matter which direction it is viewed from.

He may have been a junkie for ten years and trashed all his friends, but even when he's gone cold turkey don't expect him to say sorry. He's a spherical asshole.
