It's common for members to have the club's name "Sons of Anarchy" inked on their backs, indicating their lifelong dedication to the club. The process of getting inked in the context of SOA is deeply ritualistic and represents a rite of passage for the members. It's a physical manifestation of their identity and allegiance to the brotherhood that defines their way of life.
