Any woman or man that keeps up on the current trend of dressing in several different layers of eclectic, unmatching clothing. Common examples are girls with colorful miniskirts on over jeans and sheer sweaters over bright t-shirts, and guys with cardigans over plaid and vintage fake leather jackets with scarves. Named so because of their often hag-like appearance due to their layered, unmatching clothing.
My urban campus is overrun with urban hags.
Mary used to be an urban hag until someone tried to offer her money one day.
