It's the combination of caucasian + audacity. When certain people use their privilege to attack people of color. They may do things like call the police whilst your having a friendly family bbq. Or profess that you need a permit to sell cold water on a hot day, when they themselves don't have their shit in order. It's okay for them to have rights, but because of your color, race or religion, you are not entitled to the same freedoms or rights. The caucacity of it all!
1.) A punk-ass coward with little or no backbone. He feels he has to lie in order to fit in with the real men. Usually afraid of anything challenging. 2.) A general name to refer to a dude you don't know. As in, "All right, buster, this time you're going down for the count." or "Look here buster, I didn't sign up for this shit!" 3.) A faux gang member.
