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.
