Neo-Nazi being harassed by street punk. Notice the 'SS Bolts' ring he's wearing.

Originally a Nazi symbol signifying the Schutzstaffel (SS), Heinrich Himmler’s police forces, whose members ranged from agents of the Gestapo to soldiers of the Waffen SS to the guards at concentration and death camps.

The symbol is frequently seen in neo-Nazi tattoos and graffiti and characterizes the beliefs of neo-Nazis and racist skinheads – violence, anti-Semitism, white supremacy and fascism.
