The Decade of the Poseur

Every scene has its poseurs, its wannabes,the ones who try too hard to belong but who don't have cred. The noun poseur is defined as "a person who pretends to be what he or she is not : an affected or insincere person."
Poser already has meanings in English: "a person who poses" and "a puzzling or baffling question" . Those senses derive simply from corresponding meanings of our verb pose: "to assume a posture or attitude for artistic purposes" pose for a photograph and "to set forth for attention or consideration" pose a question or riddle. Notably, there is also the sense of pose meaning "affect an attitude or character usually to deceive or impress," as in posed as a doctor to gain entrance to the ward.
