A "fraternity" of ugly Asian juveniles who think their shit don't stink. This group is generally comprised of the Asians with the smallest dicks and biggest heads (not under the pants, of course).

Although they claim to be a fraternity, GBs are nothing more than a band of socially retarded douchebags who think they run shit everywhere they go just because they've "earned" letters that stand for Gay Boy.
