Bobkes

Bobkes, a Golem who works for a coal merchant in Ankh-Morpork, is an incidental character referenced by Dorfl in Feet of Clay as one of the new wave of emancipated golems in the city who will be working to buy out their own contracts.

Annotation

bupkis, bubkes or in the expanded form kofebupkis, is a Yiddish word having something in common with the Dwarfish term tra'ka, denoting a thing, concept or substance which is trivial, slight, or beneath notice, perhaps even somewhat distasteful. (kofebupkis means "excrement of a goat")
