n. 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.
