Wigger (alternatively spelled wigga, whigger or whigga) is a pejorative slang term for a white person who allophilically emulates mannerisms, slang, and fashions stereotypically associated with urban African Americans and urban Black British and Caribbean culture, especially in relation to hip hop culture and British Grime/Garage scene.
The term most likely stems from a portmanteau of the word white and the derogatory term nigger. The word is considered offensive by some because of its similarity to nigger in addition to reflecting stereotypical notions about urban blacks. Because of this in many communities the term for a white person that emulates urban African-Americans is "whamma", which is a play on the word "bama" which means a thuggish or rude African-American.
The phenomenon of white people adopting stereotypical black mannerisms, slang, and apparel 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 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 Norman Mailer essay, "The White Negro: Superficial Reflections on the Hipster"." It was later seen in the Zoot suiter of the 1930s and 1940s; the hipster of the 1940s; and the beatnik and rock and roller of the 1950s.
