I was trying to think up an XBL gamertag that didn't contain any "Snipes", "Majiiks", "CoD", "Alucards", "Boi", real name, birth date, foreign accented characters, arbitrary numbers, X's, I's, random spaces, l33t typing, alternating caps or doubled letters; but was short, snappy, reflected how I play, stood out and made literal sense.
That was 5 years ago. I try to keep my username the same but sometimes I fancy something different. Like a second character on a game or something: I now have a pool of epic username, some are quite original and roll off of the tongue and could pass as an actual name, but Bvenged was the first that sparked my innovative streak. It's one of the worst but the one I'm attached to and most associated with.
My Youtube channel is "Bvenged505" because I made the Bvenged channel, it bugged up, so I deleted it and remade it but apparently the "name is still taken" despite nobody on youtube having the account. That's the only time I have fallen out of line with usernames.
I'd rather not share the others out until I've become more established online with them.

the last thing I want is to see a "new" member with the name of one of them stealin' my persona.
