A super square. A major douche bag. A male typically ranging between the ages of 17-28 who thinks he has swag, but really has no swag. Sometimes a chad will will be wearing any type of Jersey Shore Paraphernalia and might be seen with a stupid hair-style.
The words origin's trace to Murrieta, CA in early 2011 where a group of obnoxious 21 year olds went to Vegas for the weekend and made a profound realization that anybody with the name Chad usually is a square. They spent the entire weekend drunk on the Las Vegas strip calling every guy that walked by a chad.
