Mucophagy

From Freepedia

Mucophagy (literally mucus-eating, also referred to colloquially as picking one's nose and eating it although the nose itself is not actually eaten) is the consumption of the nasal mucus, boogers, and other detritus obtained from nose-picking. It is a common but highly taboo activity and is almost universally regarded with disgust by others, even by those who participate in this activity themselves.

Some research suggests that mucophagy may be a natural and even healthy activity, which exposes the digestive system to bacteria accumulated in the mucus, thereby helping to strengthen the immune system.

Mucophagy is one of a family of behaviors known collectively as pica.
