This word isn't in the OED. It was added to Wikipedia (non-mobile listing) in 2003 by a user who called himself "Harry Potter" and who specializes in popular culture film and gaming listings.

Mr. "Krinkle" just defined his use of the site in the way that serious users of Mudcat see him - he is a sociopath who treats it like a plaything, where he can muck about and try to stir up trouble. He's a self-identified troll. The evidence is clear, and Jack the Sailor nailed it.
