people make fun of drinking games but man i will love gamified alcohol until the day i die. we used to play this one called Stump where you flip a fuckin hammer in the air and smash nails into a tree stump. that's objectively the most fun thing you can do.
The Roxanne drinking game is a good way to start a night. Divide the room into two teams, one drinks on "Roxanne" the other drinks on "put on the red light".
