-čuga

First attested in the late 1970s. According to Babić, it has spread from the word cr̀nčuga (“nigger”) (originally formed as crnc- + -juga), which was reanalyzed by native speakers as if being composed of cȓn (“black”) + -čuga. The word cr̀nčuga was the most common pejorative in subtitled American films and television as shown on Yugoslav television stations, acting as a calque for the English word nigger.
