The 64 oz challenge truely is a gentelmens game.
People take turns trying to drink a 64 oz cup of water as fast as they possibly can in two minutes. This will ALWAYS result in puking. However you are not allowed to puke while you still have water to drink. If you do puke before the water is gone you still have to finish the water, or forever be called a pussy bitch.

To prepare your 64 oz cup fill it till the water is about a half inch away from the top. Also have someone else carry a mug of water. Go outside (don't want to puke inside). Pour the mug into the 64oz cup until it is to the brim. Have someone ready with the timer to count down from three. Now you're ready to 64 that shit to the motha fuckin brim.
"Damn dude, did you see him do the 64 oz challenge last night? He puked for a good minute after."
