shaved head; person with a shaved head
Archaic term for a shaven head or a person with a shaven head, often associated with Buddhist monks or young acolytes. Not used in modern everyday language.
In old tales, a young acolyte called a 'blue monk' appears.
Compound of 青 (ao, 'blue/green', here possibly indicating youth or inexperience) and 坊主 (bōzu, 'Buddhist monk' or 'shaven head'). The exact historical derivation is uncertain.
