A metrosexual is a clotheshorse wrapped around a dandy fused with a narcissist. Like soccer star David Beckham, who has been known to paint his fingernails, the metrosexual is not afraid to embrace his feminine side. Why "metrosexual"? The metro- (city) prefix indicates this man's purely urban lifestyle, while the -sexual suffix comes from "homosexual," meaning that this man, although he is usually straight, embodies the heightened aesthetic sense often associated with certain types of gay men.
Mark Simpson invented this term in 1994, and it drifted slowly from one media source to another throughout the rest of 1990s and early 2000s. Then Simpson wrote another article about metrosexuals in the online magazine Salon.com on July 22, 2002, and the term took off. Since then it has been picked up by thousands of media outlets, has made numerous TV appearances, has spawned at least a couple of books, and has been dropped in untold numbers of cocktail party conversations.
There is no escaping the metrosexual.
