Mucophagy (literally mucus-eating, also referred to colloquially as picking one's nose and eating it where "it" refers to the picked mucus and not to the nose) 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. A study has however shown that mucophagy can also be healthy as it gives a boost to the immune system.

Mucophagy is one of a family of behavioral appetite disorders known collectively as pica.
