Two-A-Days, or sometimes known as Hell Week, is a term in football to describe when a football team has practice twice a day: in the morning, and in the afternoon or evening. Two-A-Days are usually done the beginning of fall, such as the end of July or mid-August, but are sometimes done on a daily basis for some teams.
The type of haircut sported by many players in the MTV show "Two a Days". Also very popular among southern males in general. To get a Two a days, one has to grow out their hair out front and flip it to the side while the sides and back are cut shorter.
Alex, on the Hoover High Bucs, has the Two a days. No, that doesn't refer to his football practice, it refers to his haircut.
