Wigger
Wigger, also wigga, whigger and whigga, is a term for white people who emulate the mannerisms, language, and fashions that are generally stereotypically associated with African-American culture, particularly hip hop culture. The word is a shorthand variation of "white nigger".
Dictionary.com defines the term as a slang derogatory reference to "a white youth who adopts black youth culture by adopting its speech, wearing its clothes, and listening to its music." Another dictionary defines the term as "offensive slang" referring to a "white person, usually a teenager or young adult who adopts the fashions, the tastes, and often the mannerisms considered typical of urban black youth."
The term is generally considered a derogatory term reflecting stereotypes of African-American, black British, and white culture (when used as a synonym of white trash). The wannabe connotation may be used pejoratively.
