Some nations treat any sex with an individual of diminished or insufficient mental capacity to give consent, regardless of age, as rape.
Autocannibalism happens when a person eats themself. In endocannabinoid cannibalism, a neighborhood of like-minded people eats somebody of their group. In fashionable instances there are five particular classes of cannibalism; first amongst them is symbolic cannibalism, one which resides in the summary, spiritual realm.
While no actual flesh is consumed in symbolic cannibalism, it's a far different matter for survival cannibalism. This encompasses a spread of behaviors from the innocuous - chewing one's fingernails, or eating the placenta after giving birth (which borders up towards realized cannibalism) - to the decidedly gross, as within the fellow in Japan who had his genitalia surgically removed and then cooked and served them at a pay-to-dine dinner social gathering.
Perhaps you're a bit of nervous or simply a creature of behavior, but chewing your fingernails right down to the fast is one thing you've got done for years.
