Think higher or lower vibes...The bigger or smaller penis card game starts with the dealer flipping over a card to the player on their right. This player must then guess if the penis on the next card will be bigger or smaller. If the player gets it wrong, they drink a shot or drink for the number of seconds corresponding to how far their guess was off.

Want to simplify it? Just add a truth or dare element, take a shot, or remove a piece of clothing!
