 The phenomenon of white people adopting stereotypical black mannerisms, speech, and apparel–which in the general case is called allophilia–has appeared in several generations since slavery was abolished in the Western world.The concept has been documented in the United States, Canada, United Kingdom, Australia and other white-majority countries.An early form of this was the "white negro" in the jazz and swing music scenes of the 1920s and 1930s; as examined in the 1957 Norman Mailer essay "The White Negro".
