My favorite is drunk driver (aside from BEIRUIT).
Played with a deck of cards, the dealer cycles around the table and asks each person question one (Q1) - get it right and dole out the drinks, get it wrong and they're yours. When its gone around once, move to to Q2, etc.
Q1: 2 drinks - red or black
Q2: 4 drinks - higher or lower (from first card)
Q3: 6 drinks - inside or outside cards from first 2
Q4: 8 drinks - suit
Then you set up a 5-4-3-2-1 pyramid with the remaining cards. Everyone memorizes what they've got and flips them over. Then the game's like bullsh!t where you flip each card and tell someone to drink if they've got it, call bs and either you or they drink double. First row is 2 drinks, 2nd is 4, etc, and the last top card is finish your drink. End round one - restart 😉.
Sounds long but with a good dealer you can get those cards out fast enough that each round takes under 5 minutes.
