What is "dob-dob"

A dob-dob ( or in some sources ldab ldob) is a member of a type of Tibetan Buddhist monk fraternity that existed in Gelug monasteries in Tibet such as Sera Monastery and are reported to still exist in Gelug monasteries today, although possibly in a somewhat altered form. The status of dob-dobs tended to be somewhat ambiguous and they were generally the less academic monks who had an interest in sports, fighting and other 'worldly' matters.
