Origin: 1545–55; < Latintrōglodyta < Greektrōglodýtēs one who creeps into holes, cave dweller, equivalent to trōglo- (combining form of trṓglē a gnawed hole; cf. trogon) + dý(ein) to creep into + -tēs agent suffix
"cave-dweller," 1555, from L. troglodytae (plural), from Gk. troglodytes "cave-dweller," lit. "one who creeps into holes," from trogle "hole" (from trogein "to gnaw;" see trout) + dyein "go in, dive in." Slang shortening trog "obnoxious person, boor" is recorded from 1956.
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.
