My username is a bit of a weird one, I know. Here's the backstory to mine:
When I was a little'un, I was very impressionable, and I became very obsessed with damn near everything I lay my eyes on. At the time of my username's conception (I wasn't even in middle school, I believe, when I first used it in some forum about Pokemon), I had become completely obsessed with the webtoon of a guy who I still admire and relate to to this day, Niko Anesti.
GEOweasel, it was called. At the time, it wasn't the most polished or funny thing in the world, but hey, I was tiny, and stupid.
Which leads me to the next half of my nickname. Did any anime fans catch it? Yes, it's
FLCL. Anyone who knows me knows I'm not a big fan of most Japanese animation/comics. I know there's a lot of people on the good ol' 'Temp who think otherwise, so I'll leave my opinions at that. The fact is, I don't like anime/manga. But years ago, I had an older cousin who absolutely loved Japanese animation/comics. He got me into FLCL, a crazy, confusing, and cryptic OVA that is hailed by those who can fathom its rollercoaster-esque storyline. I was 12 or so when he showed me it, and I couldn't comprehend a lick of it, but he seemed to like it, so I became horrendously obsessed.
So there ya go. "GEO" from GEOweasel, and "FLCL" from, well, FLCL. I'm not fond of either parts of it these days, but it's original, and easily-recognized, so it sort of stuck. I pronounce it as "Geo-flickle". Maybe I'll get it changed someday, haha.
