Anus cave

When an individual is too much of an asshole and a new term is needed to describe how big of an asshole this individual is.

Guy 1: David just made fun of me for working at Wal-Mart.
Guy 2: but David is unemployed....
Guy 1: He's seriously the biggest asshole i've ever met, he's more than an asshole I can't even describe it.

Guy 2: He's an anus cave.
