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/rap culture. The word is a portmanteau 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."
