ALTERNATE NAMES: Supreme White Power
SWP is an acronym for the white supremacist slogan "Supreme White Power." It seems to have originated on the West Coast, probably in California's prison system, though it has spread from there.
Supreme White Power and SWP are both common prison tattoos. One popular version displays the words "Supreme White Power" in a circle around a swastika made up of battle-axes. Usually, below the swastika is a Viking ship.
