A bunch of us had been aggressively moshing around in a newsgroup (w.katzenjammer).
Behind the scenes, in email, we began communicating and discovered that we actually liked each other.
One day a fellow who went by Riotgear in the newsgroup declared that we were like digital knights, and in fact whether we liked it or not we were all part of something called "Order Of The Illustrious Katzenjammer Knights Of Fire".
Like most everything else we did in public we took it to absurd levels... knight/medieval themed avatars and signatures, etc.
The reactions we got made it all worth it and provided much amusement.
"OOTIKKOF" eventually became "OOTIKOF" when a fair number of us no longer posted in or even had access to the MSNTV katzenjammer newsgroup.
...and that's about it, really.
