Shag

A shag is basically a haircut that looks like a rattail mullet but not really, it is widely by Hispanic gangbangers in Chicago widely from the Latin Kings to Maniac Latin Disciples

The cut is simple and easy to do if the person has long enough hair where its basically buzzing off the hair all around except for the back end where it is left there long. Though I won't highly recommend it because you will look terrible and possibly shot. (In the wrong Chicago neighborhoods)

Juan: Damn what the hell is the cut Jose is rocking?
Hector: That shit? oh its called a shag and I think it mean he claims something.
