The use of the term "American youth culture" may invoke images of urban hipsters, suburban wiggas, cheerleaders, graffiti writers, skater kids, youth of the African Diaspora with oversized pants slung low on the hips, or lesbian zine writers, but rarely does such a term invoke images of girls donning burkas, even if they are also in sequined prom dresses.
