troglodyte

n. [Commodore] 1. A hacker who never leaves his cubicle. The term gnoll
(from Dungeons Dragons) is also reported. 2. A curmudgeon attached to an
obsolescent computing environment. The combination ITS troglodyte was flung
around some during the Usenet and email wringle-wrangle attending the 2.x.x
revision of the Jargon File; at least one of the people it was intended to
describe adopted it with pride.
