Hipster.

"The hipster is that person, overlapping with the intentional dropout or the unintentionally declassed individual—the neo-bohemian, the vegan or bicyclist or skatepunk, the would-be blue-collar or postracial twentysomething, the starving artist or graduate student—who in fact aligns himself both with rebel subculture and with the dominant class, and thus opens up a poisonous conduit between the two."
