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.
