(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 e-mail 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.
