Yarpie/yarpy

Pejorative slang for a white male South African derives from the Afrikaans Japie, which is a diminutive of Jaap which in turn derives from the Afrikaans Jakobus (James in English). From the late 19th/early 20th century a japie or plaasjapie, which means a farm boy in Afrikaans, came to mean a simpleton and that’s why today white South Africans generally object to being called yarpies or japies.
