A food fight is a form of chaotic collective behavior, in which food is thrown at others in the manner of projectiles. These projectiles are not made nor meant to harm others, but to simply ignite a fight filled with spontaneous food throwing. Food fights may be impromptu examples of rebellion or violence; however, they can also be planned events. In organized food fights, the food "weapons" are usually all of one kind, or of a limited variety. An impromptu food fight will use whatever food is on hand.
