Troglodyte
<jargon> (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.
