I have been Wowbagger almost since time immemorial, for obvious reasons.
Sometimes the neural ganglia recall why this was, and today is one of those days.
Some time back in the late 1990s, and the Internet became a thing that almost everybody didn't have, Dez was at Swansea University "studying" computer science. Because he was the geek he still is, he bought a modem from somewhere and we managed to get "online".
Swansea Uni had a talker called Milliways which one or more of them had written. Those who don't know, and that's almost everyone, will be impressed by the fact that Prof. Alan Cox was a Swansea Uni man and he had quite a bit to do with Linux's ability to tell printers what to do, to the extent that Swansea Uni got a mention in the credits when Linux booted up. For all I know it still does. So Swansea was possibly slightly ahead of the game in Things Like This.
Anyway, back to the Talker. It was almost entirely based upon HHGTTG and TMR* so people tended to adopt characters' names from either colossus of popular culture. Thus there was an Arthur, and almost certainly a Florence. Given, as mentioned above, that I became a member of that talker simply because we were about the only parents of students to have an internet connection, it was obvious that as by far the oldest there, I had to be Wowbagger. And so I am. I also quite enjoy insulting people.
*The Magic Roundabout
Edit: actually, come t think of it, I think we were online before he started at Uni, which was 1997. When he was still at Southend High School he wrote the schools "intranet" using HTML. I suspect that we were originally singed up in about 1996.
