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.
