A variation of quarters my buddies and I made up when we were shitty. You can play with however many people you want. Start with 7-10 cups filled with beer in a triangle.
Everyone has their own quarters and you can shoot at any cup. Whenever you make a cup you take it out and place it by your side. Once the last cup is made everyone gives their cups to whomever they want for that person to drink.
This game can lead to extreme drunkness and many angry arguments over why you passed those cups to Friend A instead of Friend B.
