-oid

[from Greek suffix -oid = in the image of]

Used as in mainstream slang 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 box (Real Modems run at 28.8 or up); a computeroid might be any {bitty box}. The word keyboid could be used to describe a {chiclet keyboard}, but would have to be written; spoken, it would confuse the listener as to the speaker's city of origin.
More specifically, an indicator for `resembling an android' which in the past has been 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 popularization of the term {droid} in Star Wars and its sequels. (See also {windoid}.)
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 I can personally confirm only that they were already common in the mid-1970s --ESR].
