Drinking game

Fanon Alert! This section contains non-canon material created by fans inspired by the show.

Drinking games involve drinking a pre-determined amount of alcoholic beverage whenever a pre-established condition has been met. The objective is to win via others becoming too drunk to continue participating, or sometimes to simply increase the enjoyment of the related activity through inebriation. In the fandom of Lost, one such drinking game is called "Jackface" based on the expressive and varied facial expressions of Matthew Fox; another example is drinking whenever Hurley says the word "Dude."
