VATICAN CITY—Vatican spokesman Joaquin Navarro-Valls said Monday that metrosexuality, the trend of heterosexual men co-opting the aesthetics of homosexual men, is strictly prohibited under Catholic doctrine. "The truly faithful will avoid the temptation to adopt this hip urban lifestyle," Navarro-Valls said. "The devout Catholic must remain on the path toward salvation, no matter how good he'd look in an Armani pullover, and no matter how much he might covet his neighbor's set of Williams-Sonoma lobster forks." Karl Weis, director of the New York-based activist group Freedom From Religion, responded to the ban by stating that "metrosexuality is so 2003."
