terminal junkie
     
        (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}.
