terminal junkie
n.
[UK] A {wannabee} or early {larval stage} hacker who spends most of
his or her time wandering the directory tree and writing {noddy}
programs just to get a fix of computer time. Variants include terminal
jockey, console junkie, and {console jockey}. The term console jockey
seems to imply more expertise than the other three (possibly because
of the exalted status of the {console} relative to an ordinary
terminal). See also {twink}, {read-only user}. Appropriately, this
term was used in the works of William S. Burroughs to describe a
heroin addict with an unlimited supply.
