Dick is a party game in which you use direct quotations from Herman Melville's 1851 novel, Moby-Dick, to propose answers to mock-serious questions. It is a game about playing irreverently with words and meanings.
In each round, one player serves as a judge and reads aloud a question or fill-in-the-blank prompt from a green card. The other players submit white cards, each containing a verbatim quotation from Moby-Dick, as suggested completions for the prompt. The judge reads all the submissions aloud and chooses the best one, construing "best" however he or she sees fit. The winner keeps the green card, everybody replenishes their white cards, and the role of judge rotates to the next player. At the end of the game, whoever has the most green cards wins.
The game depends on understanding the particular wit of the other players and strategically playing answers to appeal to each round's judge. The sheer irreverent weirdness (sexual and otherwise) of Moby-Dick is what makes the game exciting and hilarious.
