-oid
     
         (from "android") A suffix used as in mainstream
        English to indicate a poor imitation, a counterfeit, or some
        otherwise slightly bogus resemblance.  Hackers will happily
        use it with all sorts of non-Greco/Latin stem words that
        wouldn't keep company with it in mainstream English.  For
        example, "He's a nerdoid" means that he superficially
        resembles a nerd but can't make the grade; a "modemoid" might
        be a 300-baud {modem} (Real Modems run at 144000 or up); a
        "computeroid" might be any {bitty box}.
     
        "-oid" can also mean "resembling an android", which was once
        confined to science-fiction fans and hackers.  It too has
        recently (in 1991) started to go mainstream (most notably in
        the term "trendoid" for victims of terminal hipness).  This is
        probably traceable to the popularisation of the term {droid}
        in "Star Wars" and its sequels.
     
        Coinages in both forms have been common in science fiction for
        at least fifty years, and hackers (who are often SF fans) have
        probably been making "-oid" jargon for almost that long
        (though {GLS} and {ESR} can personally confirm only that they
        were already common in the mid-1970s).
