poseur

Poseur (or poser) is a pejorative term, often used in the punk, heavy metal, hip hop, and goth subcultures, or the skateboarding, surfing and jazz communities, to refer to a person who copies the dress, speech, and/or mannerisms of a group or subculture, generally for attaining acceptability within the group or for popularity among various other groups, yet who is deemed not to share or understand the values or philosophy of the subculture. While this perceived inauthenticity is viewed with scorn and contempt by members of the subculture, the definition of the term and to whom it should be applied is subjective. While the term is most associated with the 1970s- and 1980s-era punk and hardcore subculture, English use of the term originates in the late 19th century.
