In the 2000s, white supremacists created a handsign intended to memorialize the Schutzstaffeln or SS of Nazi Germany, Hitler's secret police, political army, and concentration camp guards. The handsign utilizes both hands to make a lightning bolt symbol, as a pair of lightning bolts was the main symbol of the SS.
Members of the white supremacist group Volksfront have used several handsigns to represent their gang. A common one-handed sign features the fingers of the right hand divided into a "V" shape, often held over the chest. A two-handed sign uses one hand to make a "V" shape (using two or four fingers) and the other hand to make the shape of the letter "F."
Zyklon B was the name of the gas used to kill over a million victims, most of them Jews, in the death camps constructed by Nazi Germany during the Holocaust. Because of its association with killing Jews, Zyklon B has been adopted as a symbol by modern-day white supremacists, who often use it to make sick jokes about killing Jews.
"Blut und Ehre" is a German phrase that translates into "Blood and Honor;" it was popularized by the Nazi Party (as a Hitler Youth slogan and elsewhere). Since World War II, this German phrase (and even more so for its English translation) has commonly been used by white supremacists in Europe, the United States, and elsewhere.
The Nazi or Hitler salute debuted in Nazi Germany in the 1930s as a way to pay homage to Adolf Hitler. It consists of raising an outstretched right arm with the palm down. In Nazi Germany, it was often accompanied by chanting or shouting "Heil Hitler" or "Sieg Heil." Since World War II, neo-Nazis and other white supremacists have continued to use the salute, making it the most common white supremacist hand sign in the world.
