Now here's a long one for ya:
My very first name on the interwebs was Videog133, but that was on some useless game site. I sometimes still use that name when I need a second identity.
Anywho, my "second" name was KirbylikesVid, which was the name I used on the first forum I ever joined,
Animal Crossing Community (Yes, that was my first one, lol.) This name came from the fact that I liked Kirby at the time, (and still do lol) and Vid was the name of my Animal crossing town. So the name was good for that forum.
Eventually, I started going to other things, and I decided I needed a better name for the interwebs, that was moar universal. I then asked for help on a different forum, and someone came up with "KirbylikesIt". I decided to stick with that as a name for universal purposes, and to use other "sub-names" for certain places. In other words, things like "KirbylikesPoG" (Don't ask, lol.)
Here's a quote from that first forum on the origin of "KirbylikesVid":
I'm sure you know Kirby, right? You know, pink dude, made by Nintendo? I like him, or is Kirby a her?
I'm proud (well, not exactly...) of my towns, both named Vid. I want Kirby to like my town. BAM! You understand, right?
And that's it. I hope I interested you for 5 minutes :P
