Poseur

"Poseur" refers to someone who poses for effect, affects an attitude to impress others, or pretends to belong to a group, and the word is also used for an artist's model. Within subcultures such as punk, heavy metal and goth, it is often a pejorative for people who copy a group's dress or mannerisms without sharing its values. Examples cited include Oscar Wilde, James Whistler and Aristophanes' portrayal of Socrates in The Clouds, while the term appeared in punk songs such as X-Ray Spex's "I Am a Poseur". The English word derives from the French poseur, which comes from the Old French poser, meaning "to put, place, or set."
