Robert A. Clift's documentary, "Blacking Up: Hip-Hop's Remix of Race and Identity," questions white enthusiasts of black hip-hop culture. The term of art "wigger" "...is used both proudly and derisively to describe 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 Justin Bieber, Vanilla Ice (popular music's ur-wigger) and Eminem." A review of the documentary refers to the wiggers as "white poseurs."
