Russian Water
The object of the game is to hold water in your mouth the longest. It is necessary to have multiple players. Player 1 takes the first sip of H20 and then lays down. Player two then takes a sip and lays down directly next to the person. In order to make your opponent spit the water out, you must make them laugh. They can do one of two things,

A: Spit the water everywhere
or B: Hold the water in their mouth, causing them to choke, Dangerously.
HINT, if the player is determined to win, and they keep choking, eventually they will throw up.

It is called Russian water because:
Russian as in Russian roulette

THIS is potentially lethal if played enough times. Commonly mistaked as VODKA.
I got yelled at by my mother and my best friend thought that some Russian Water would cheer me up.
