Nose-picking is the act of extracting nasal mucus with one's finger (rhinotillexis) and may include the succeeding action of ingesting the mucus picked from the nose (mucophagy). This action is condemned in most cultures; societies try to prevent development of the habit and attempt to break it if already established. Mucophagy is a source of mockery and entertainment in the media.
