Egging

Although a food item, eggs are sometimes thrown at houses, cars or people generally on Halloween. This act, known commonly as egging in the various English-speaking countries, is a minor form of vandalism and, therefore, usually a criminal offense and is capable of damaging property (egg whites can degrade certain types of vehicle paint) as well as cause serious eye injury . On Halloween, for example, trick or treaters have been known to throw eggs (and sometimes flour) at property or people from whom they received nothing. Eggs are also often thrown in protests, as they are inexpensive and nonlethal, yet at the same time very messy when broken. John Prescott was egged by a rural protestor, which sparked controversy when he retaliated.
