Wigger
Wigger is a derogatory slang term used to describe a person, usually of European descent and with pale skin (often described as a "Caucasian" person in North America), who dresses, speaks, or otherwise behaves in a manner that is stereotypically associated with African-American culture — for example, speaking in Ebonics. The term is a portmanteau word combining the words 'white' and 'nigger', or 'wannabe' and 'nigger'.
The condition is sometimes seen as evidence for a lack of identification with or interest in a person's own culture or simply as an interest in subcultures such as hiphop and 'street' which are typically associated with blacks.
The Offspring song Pretty Fly (For A White Guy) is a famous song about "wigger" culture.
