GTKRWN (also GTK RWN) is a white supremacist acronym for the racist and anti-Semitic slogan “Gas the Kikes; Race War Now.” Occasionally, white supremacists may only use the first part of the acronym: GTK. The slogan appears to have been created around 2014 and is most associated with the alt right and neo-Nazi segments of the white supremacist movement.
The phrase is used as a “call to action” slogan by some white supremacists, but some others use the acronym to describe a certain portion of the white supremacist movement itself. In this latter context, the acronym is typically used as a somewhat negative reference to less sophisticated and more headstrong, outspoken or crudely violent white supremacists. For example, one 8Chan user admiringly posted in June 2018 about people able understand Nazism “beyond GTKRWN and Hitler pictures.”
