A portmanteau of sarcastic and bastard. A sarcastabastard always has something snarky and sarcastic to say in response to anything you throw at him and is a general pain in the ass.

Sole redeeming quality is how hilarious it is to watch them roast people.
Oh, my god. Curtis is such a sarcastabastard. I don't think I've ever heard an honest word outta that guy's mouth.
