Everyone who has done that must take 1 drink. The Player that flipped this card states something they have never done. Last player to touch the floor after this card was drawn takes 1 drink. This continues clockwise until the last player puts their drink down. The next player clockwise then has to start drinking his/her own drink until the player before him/her puts their drink down.
The player who drew this then proceeds to drink as much of their drink as he wants. Players take turns flipping cards from a standard deck of cards and performing the action on the card.
