A derogatory term for someone who comes from or resides in Ruz, or is simply of Ruzi ancestry. It was coined by people from nations invaded by the Ruzi Empire in Emperor Klaudiusz's "path of power".
This offensive slang was popularized in Jutland during the BRFH Blockade. Since it is a racial epithet against the Ruzi people, nowadays it is considered taboo to speak in public or those from Ruz.
