i had no idea there were rules.
“Pillow fights are a game played to let out energy and rage in a mostly harmless way. In a pillow fight players can split up into teams or just fend for themselves. Then each player either starts off with a pillow or has to find the pillows hidden throughout the house. Then each player starts to attack the other player with the pillow, trying to avoid being smacked by a player in the head. They usually aim for the legs and stomach area. In this game there is no winner. The game ends when all the players are tired or the players just decide to surrender. This game takes more skill than one would think. Trying to attack their opponent while trying to defend themselves from the crashing blows of the opponents pillow. Overall the game is just senseless fun and is not played for a prize but for its entertainment value.” -wiki
