The definition of Cannibalism is put as:

-noun 1. the eating of human flesh by another human being. 2. the eating of the flesh of an animal by another animal of its own kind. 3. the ceremonial eating of human flesh or parts of the human body for magical or religious purposes, as to acquire the power or skill of a person recently killed. 4. the act of pecking flesh from a live fowl by a member of the same flock. 5. the removal of parts, equipment, assets, or employees from one product, item, or business in order to use them in another. 6. the acquisition and absorption of smaller companies by a large corporation or conglomerate.

According to this definition, eating part of one's self would not be cannibalism but would be better categorized as autophagia. Comment retained:

"Yes! you are considered a cannibal, and you must be locked away, and eat vegtables until you expolde. What to do first:Here is my advice: lock yourself into an attic and etc, and you can only eat vegtables for three weeks until you are clean. Here is some more advice: DON'T EAT PEOPLE!" == ==
