1) A reference to Aryan Brotherhood prison circles according to the ADL. The numbers 13 and 12 translate alphanumerically to AC and AB, which according to the ADL mean “Aryan Circle” and “Aryan Brotherhood” respectively. Many white supremacists will wear this on shirts and other paraphernalia.

2) A reference to ACAB (All Cops Are Bastards). Similar to the first definition the numbers can be translated alphanumerically. While many activists will put the numbers on their clothing, a number of white supremacists in disguise will also do the same as a way to conspire with other members of the brotherhood in secret.

1: A reference to Aryan prison groups according to the ADL. The numbers 13 (Aryan Circle) and 12 (Aryan Brotherhood) substitute letters for numbers in order to create the number scheme 1312.

2: A reference to ACAB (All Cops Are Bastards). Similar to the first definition the naming scheme substitutes letters for numbers.

-The numbers are often put on shirts, hats and other clothing paraphernalia. Both uses of the word are widely used by both BLM/Antifa groups as well as Aryan supporters alike. Some people will even wear it in support of Aryan ideals while feigning opposition to police.
