A person holding an alcoholic beverage in each hand. Often seen at keggers, ball games, or other places where the line for a drink is rather long. Individuals will often get two drinks at a time. When one is finished they get back in line. They can then enjoy the second beverage while waiting. That way they never run out and risk ruining their buzz.
