Rat-Bastard

1. A particularly nasty piece of work. A real jackass. Someone you’d rather beat with a brick until they stop twitching then interact with. Not a nice chap by any means.

2. A jocular way to compliment your friend. Sly, sneaky, clever. Works with Magnificent Bastard as well

Option 1:
That rat-bastard stole my car!

Option 2:
You rat-bastard! How are you?
