Cheatin Rat Bastard

CRB is usually associated to those who WIN on a consistant basis, with no basis of provability. Someone who is either lucky, on a roll, or maybe just flat good, and are scourned by the outsider and his peers, more than likely, out of pure jealousy.

2. He always wins, "Cheatin Rat Bastard!!!!!!"
