With little to go on in the way of explanation or description from YouTube, this looks to be a bastardized game of beer pong combined with Flip Cup. I’ve watched it a few times while focusing on the girl team on the far end (because they won) and I still can not figure out the rules or the goal of the game. Maybe you can? If you do, please post your interpretation of the rules in a comment below.
