Aryan Brotherhood of Texas (hand sign)

The Aryan Brotherhood of Texas (ABT), a large and violent racist prison gang, uses a hand symbol consisting of a raised index finger and raised ring and little fingers (or the reverse), signifying the numbers 1 and 2. Substituting letters for numbers 1 and 2 stand for A and B, or Aryan Brotherhood. Sometimes ABT members may use a two-handed variation in which one hand "throws up" one digit and the other hand (belonging to the same or a different person) "throws up" two digits, again signifying 1 and 2.
