A game involving two or more players and any number of drinks, fluids, whatever have you (note: this game is best played under the influence). Imagine hot potato, but replace your usual projectile with drinks, and swap out throwing a ball or whatever with spitting the liquid into the next player's mouth, otherwise known as the "witch's brew".
After the first player has gargled for 30 seconds, they spit into the next player's mouth, and are given the opportunity to add something to the brew. Spitting out the brew (the witch's brew equivalent of dropping the "hot potato") results in elimination. Rinse and repeat the process until someone either wins by swallowing the "witch's brew" (which requires at least 4 passes of the brew between players), or is the last one standing after all others have spat out the brew.
Brody: "Ayo, did you hear this bro?"
Terry: "Nah, what's up?"
Brody: "P Diddy just got exposed for hosting competitive games of Witch's Brew at his celebrity parties."
Terry: "Sick."
