88 is often used in place of "heil hitler", with "H" being the 8th letter of the alphabet. It's a neo nazi thing (I refuse to capitalize either hitler or nazi). The wording is likely "brotherhood", standing for aryan brotherhood.
Thanks for the info. The neck tat does look like
BROTHER HOOD.
In all things if you understood what Hitler was and the whole Nazi cult its really a joke to be honest, they took religious symbols from Buddhism and Jainism and turned it into the Nazi flag, Pagan beliefs, and the concept of the super race (ubermensch) all from a man who was not an Aryan by Nazi German standards.
