I needed a username back in the day when I still played on Xbox Live. Trialtrex was one of the suggestions and the 21 was added later due to the loss of some non-premium Minecraft accounts.

I wish i had chosen something cooler

..I really want to show you how cool your username is by writing a cover of Iron-Man by Black Sabbith.

A named myself after a VST called DBlue Glitch, I suppose the meaning is interchangeable however because I do have a knack for breaking video games.
I also used it as a steam name, and after a few months of going by this name I just got used to people calling me that, so the name stuck.

For a brief period I went by Glitchponi so I was easier to find by friends on Steam (because there are hundreds of Glitch's) I don't use that anymore now, as I was sick of being associated with bronies.

My username is just scribbles....Yay uniqueness....

dicks.

that sums it up pretty much

Monocles happen to be classy as fuck; computers are pretty neat as well.

My username is so simple it is just my name. My name anderson smith and this is my username.

I'm a fan of the scp foundation an destiny, so scpdestiny seemed to make sense at the time haha

My mum came up with the username for her email and youtube account, and since i took over her youtube account in 2010 (she let me), i got stuck with the name.

I was going to think up an original username, but then I got stuck with a generic Class-D designation. :S
