A scar on one's body left by the burn of a red-hot cigarette lighter - normally a Bic lighter.

Some house rules of the drinking game "Buffalo" require that you have a "Buffalo Scar" to be a true member of the "Buffalo Club".
Guy 1: "Look at that guy's arm. He has a scar that looks like he burned himself with a lighter."

Guy 2: "Yeah, it's a Buffalo Scar. He must be in the Buffalo Club."
