Common Usenet jargon for a notional instrument used to measure the provocation level of a Usenet troll. “Come on, everyone! If the above doesn't set off the Troll-O-Meter, we're going to have to get him to run around with a big blinking sign saying ‘I am a troll, I’m only in it for the controversy and flames', and shooting random gobs of Jell-O(tm) at us before the point is proven.” Mentions of the Troll-O-Meter are often accompanied by an ASCII picture of an arrow pointing at a numeric scale. Compare bogometer, Indent-o-Meter.
