Poseur → The word originates from French 'poseur', meaning 'one who poses'. It is derived from 'poser' (meaning to pose or place), which comes from Latin 'ponere' (meaning to place). A poseur is someone who pretends to be something they are not, often by putting on a false front or attitude.
Think of someone 'placing' themselves in a certain way to appear different — that's why a poseur is someone who pretends to be something they are not.
