I picked mine because no one ever uses it and it is my unique invention. Its origin is it's my alter ego in a story that I am currently writing in my spare time.
My username came from my time in the Army. (yes I was in the Army. No I am not still in it. Medical discharge.) My company was echo company. The company mascot was the eagle. And I was in the third platoon. Put them all together and you got echoeagle3. I had never had a user name before so I have stuck with this one. It's pretty much my user name everywhere.
All my usernames have some sort of story behind them. When I broke up with a girl a while back, her friend told me "You're dumb. You're just dumb. Your emotions are completely random; no one will ever understand you or love you; you're dumb."
Random+dumb=Randumb. That's just how I roll, and the ladies love it.*
My boyfriend calls me by it. Well.. both words individually. As per the origins... well.. It's kind of embarrassing. /Show Spoiler at your own discretion.
Spoiler:
I'm into the EGL style of dress. I just..I'm a girl, and I like to feel cute/pretty, and for me that is when I'm dressed up in dark frills. I was also.. younger when I first met my boyfriend. Who's.. not. :'3 As per the Kittie part of things.. well, that's easy. I'm a snugglewhore, I adore receiving physical affection [..petting. Dx] and I perk up in response to clicking noises. I don't know why particularly, but it seems to amuse the piss out of him.
I'm not sure where I got the idea for my username. I wanted the first letter to match the first letter of my real name though.
I like my username.(´・ωï½¥`)
I chose it for two reasons:
Irony. I am named after the Goddess of Love, yet completely inexperienced.
I love history, especially everything ancient or B.C.
Gods falls under that category, so I have an expansive knowledge of mythology from all over the world.
