Pica

Pica is the psychologically compulsive craving or consumption of objects that are not normally intended to be consumed. It is classified as an eating disorder but can also be the result of an existing mental disorder. The ingested or craved substance may be biological, natural, or manmade. The term was drawn directly from the Latin word for the Eurasian magpie, a bird subject to much folklore regarding its opportunistic feeding behaviors.
