A metrodork is a straight man who embraces some aspects of an urbangay style: emotional sensitivity, refinement in taste, enjoyment of flamboyant clothing styles, and use of body care products (in other words, a metrosexual); but who spoils the effect by wearing a New York Yankees cap.
Willis carries a handbag, gets his hair styled, gets a Brazilian wax, and dresses out of Gentlemen's Quarterly; however he also routinely wears a New York Yankees baseball cap which shouts that he is a metrodork if not an out-and-out asshole.
