rat-bastard 

An extreme bastard; a real asshole. Frequently used by middle-aged trailer trash women to describe the ex-boyfriend who beat her.

I told that RAT-BASTARD if he ever hit me again I would call the law.

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?

Rat Bastard 

A supposed human who is actually lower that a human being, but to make things worse, is able to pretend to be a human being. Someone who'd likely steal from his own brothers and suck up to his in-laws

That Rat Bastard PW sucks his stupid mother-in-laws ass while never visiting his own momma
