Dob-dobs were a group of monks from the Se-ra monastery in Tibet, who began life as warriors working as laborers or collectors of yak dung, but by the late nineteenth century had evolved into monastic police, kind of prefects for the monastery.
They were well known for their homosexual liaisons, and would occasionally venture down to the nearby city of Lhasa to kidnap young boys. These forays would often lead to the other great love of the Dobdob, fighting.
Dob - dobs could easily be recognized their appearence. The skirt part of their habit was longer than usual, but they kept it kilted up rather higher than the ordinary monks. That gave them a bulky look round the thighs, which they exaggerated by swinging their buttocks as they walked.
