An archaic British slang term for a chief pickpocket or leader of a thieving gang.
Compound of 'dimber' (excellent, distinguished) + 'damber' (unknown origin, possibly 'dabber'—one who dabs/picks). Used in 17th-century underworld cant and criminal argot.
Dimberdamber is proof that thieves had job titles—it specifically meant the boss pickpocket who ran the operation, giving a weird-but-honest organizational hierarchy to historical crime!
