n. An ASCII glyph used to indicate an
emotional state in email or news. Hundreds have been proposed, but
only a few are in common use. These include:
(These may become more comprehensible if you tilt your head
sideways, to the left.)
The first 2 listed are by far the most frequently encountered.
Hyphenless forms of them are common on CompuServe, GEnie, and BIX;
see also bixie. On USENET, 'smiley' is often used as a
generic term synonymous with emoticon, as well as specifically
for the happy-face emoticon.
It appears that the emoticon was invented by one Scott Fahlman on
the CMU bboard systems around 1980. He later wrote: "I wish I
had saved the original post, or at least recorded the date for
posterity, but I had no idea that I was starting something that
would soon pollute all the world's communication channels."
[GLS confirms that he remembers this original posting].
Note for the newbie: Overuse of the smiley is a mark of
loserhood! More than one per paragraph is a fairly sure sign that
you've gone over the line.
