Fast paced drinking game where players lay down sets of cards in numerical order while also calling out one of the four types of shit suits on their cards.
When you don't have the cards you need, you can 'bluff' by playing other cards.
If someone calls Bullshit, then on your bluff then if you were bullshitting you drink up and if you weren't bullshitting then they drink up.
Make sure if playing this game, that you remember responsible drinking.
