pr0n //
[Usenet, IRC] Pornography. Originally this referred only to Internet porn but since then it has expanded to refer to just about any kind. The term comes from the warez kiddies tendency to replace letters with numbers. At some point on IRC someone mistyped, swapped the middle two letters, and the name stuck, then propagated over into mainstream hacker usage. New versions of the Mozilla web browser internally refer to the image library as "libpr0n"Compare filk, grilf, hing and newsfroup.
Hey, thanks for the etymology. I once did a search for the term's origin, but came up empty. But, I think at the time that I had misinterpreted the '0' zero character as as set of parentheses (from working with a character set that made them appear as a similar shape).
