Robert A. Clift's documentary "Blacking Up: Hip-Hop's Remix of Race and Identity" questions white enthusiasts of black hip-hop culture. Clift's documentary examines "racial and cultural ownership and authenticity – a path that begins with the stolen blackness seen in the success of Stephen Foster, Al Jolson, Benny Goodman, Elvis Presley, the Rolling Stones – all the way up to Vanilla Ice (popular music's ur-wigger...) and Eminem". A review of the documentary refers to the wiggers as "white poseurs", and states that the term "wigger" "is used both proudly and derisively to describe white enthusiasts of black hip-hop culture".
