UA Shag 

UA Shag is a shaggy hair style made famous by it's popularity at Upper Arlington High School in Upper Arlington Ohio. In the early 1990's, boys at the high school began growing their hair out, while neglecting styling products or frequent trips to the barber. The length of hair can vary from growing just over the ears all the way to shoulder length. When paired with a circle hat the hair will form 'wings', which is when the locks of hair above the ear would protrude to the sides.

Despite what you may think, chicks dig the UA Shag.
