An alcoholic drink that consists of Gatorade, Red Bull, and Everclear. Because the drink is largely made up of Gatorade and Red Bull, party goers are often able to consume large amounts. However, the addition of Everclear makes the drink very alcoholic. The drink is usually served in a jug that portrays a picture of Gary Busey.
