Where you gather 5 or more friends(male or female) and offer everyone a
glass of milk. Prepare the drinks in the kitchen, using all similar glasses except one. Quickly bust a nut into the odd glass out before pouring the milk. Bring all of the drinks to the table and let them choose their fate.
Sit back and
await your victim.
Person 1: I've played plenty of crazy
party games in my day, but that was unexpectedly gross!
Person 2: I agree! I never
would've expected to end up with a Mysterious Glass o' Milk situation at
Happy's place.
