flame
     
         To rant, to speak or write incessantly and/or
        rabidly on some relatively uninteresting subject or with a
        patently ridiculous attitude or with hostility toward a
        particular person or group of people.  "Flame" is used as a
        verb ("Don't flame me for this, but..."), a flame is a single
        flaming message, and "flamage" /flay'm*j/ the content.
     
        Flamage may occur in any medium (e.g. spoken, {electronic
        mail}, {Usenet} news, {World-Wide Web}).  Sometimes a flame
        will be delimited in text by marks such as "...".
     
        The term was probably independently invented at several
        different places.
     
        Mark L. Levinson says, "When I joined the Harvard student
        radio station (WHRB) in 1966, the terms flame and flamer were
        already well established there to refer to impolite ranting
        and to those who performed it.  Communication among the
        students who worked at the station was by means of what today
        you might call a paper-based Usenet group.  Everyone wrote
        comments to one another in a large ledger.  Documentary
        evidence for the early use of flame/flamer is probably still
        there for anyone fanatical enough to research it."
     
        It is reported that "flaming" was in use to mean something
        like "interminably drawn-out semi-serious discussions"
        (late-night bull sessions) at Carleton College during
        1968-1971.
     
        {Usenetter} Marc Ramsey, who was at {WPI} from 1972 to 1976,
        says: "I am 99% certain that the use of "flame" originated at
        WPI.  Those who made a nuisance of themselves insisting that
        they needed to use a {TTY} for "real work" came to be known as
        "flaming asshole lusers".  Other particularly annoying people
        became "flaming asshole ravers", which shortened to "flaming
        ravers", and ultimately "flamers".  I remember someone picking
        up on the Human Torch pun, but I don't think "flame on/off"
        was ever much used at WPI."  See also {asbestos}.
     
        It is possible that the hackish sense of "flame" is much older
        than that.  The poet Chaucer was also what passed for a wizard
        hacker in his time; he wrote a treatise on the astrolabe, the
        most advanced computing device of the day.  In Chaucer's
        "Troilus and Cressida", Cressida laments her inability to
        grasp the proof of a particular mathematical theorem; her
        uncle Pandarus then observes that it's called "the fleminge of
        wrecches."  This phrase seems to have been intended in context
        as "that which puts the wretches to flight" but was probably
        just as ambiguous in Middle English as "the flaming of
        wretches" would be today.  One suspects that Chaucer would
        feel right at home on {Usenet}.
