left bastard

When someone is three times as much of a right bastard than thought possible.

Inspiration: "Two wrongs don't make a right, but three rights make a left."

Person 1: Did you see him hit-and-run my car? What a right bastard he is.

Person 2: He did worse than that. He ran over a puppy and threw an empty beer can out his window. That bastard ain't a right bastard, he's a left bastard.
