1. Any set of activities or sport(s) requiring competitive consumption of alcoholic beverages.
Drunkathons usually include but are not limited to a tournament of Drinking Games i.e. Kings Cup, Beer Pong, Keg Stands, Shot Gunning Beers, etc, or in some cases racing from the bar to the liquor store in time to purchase more alcohol before 2AM. Most typical drunkathons result in nausea or vomiting by more than one participant(s) involved, and or temporary blackouts. Most drunkathons are not planned but rather a result of unrestrained drunkeness.
