A "Jimp" is a slang term used in the 2000 AD universe for an individual (usually a criminal) impersonating a Judge.
Role in 2000 A.D.Edit
Every Jimp has their own hidden agenda and reasons for infiltrating the Justice Department. These motives are usually referenced in the movies or comics in which they appear. If a Citizen is caught jimping the sentence is 10 years in prison.
