A food fight, a common staple in numerous low-budget American children films, involves the flinging of various consumable goods, including both food and beverage, across a room. A food fight typically commences with the exchange of various innocuous food items, whereupon a relatively rotund blond-haired child with a buzz cut shall stand upon a table and declare, "FOOD FIGHT!". In the same sense that the unexamined life is not worth living, an undeclared food fight is not worth fighting: an undeclared food fight, or a food fight that is improperly declared, shall typically be viewed as invalid.

Various reputable American children's networks feature food fights exceedingly frequently; it is a relatively uncommon occurrence to view either one such film or five consecutive episodes of such programming without witnessing a food fight of some sort. Unfortunately, numerous recent programs have compromised the genre, featuring declarations by relatively thin persons or even including undeclared food fights, an anathema to those schooled in the true art.
Joey, feeling rather distraught and dejected, flung his breakfast burrito haphazardly across the room. He realized his mistake when he witnessed said burrito strike another student across the face, whereupon BJ, the school fat kid, stood upon the table and bellowed out in a rich, mellifluous voice, like so many Sirens wooing Odysseus, "FOOD FIGHT!".
