Agreed. This has nothing to do with the term "metrosexual".
"Metrosexual is a neologism, derived from metropolitan and heterosexual, coined in 1994 describing a man (especially one living in an urban, post-industrial, capitalist culture) who is especially meticulous about his grooming and appearance" - Source http://en.wikipedia.org/wiki/Metrosexual
Wikipedia quotes the dictionary incorrectly. It refers to a heterosexual man, yes, but the "-sexual" postfix comes from homosexual. It's meant as a put down to straight guys acting gay.
Yes, but not a very relevant (or clever) one. Just because two words can go together doesn't make it a fit for the article's title. Something about Metropolis would probably have been better, as in, not being a denizen of the city of Metro.
Also, if you actually do consider yourself to be metro, then it's even more out of place.
