Mine's based on something that happened while I was trying out a sandbox map for Portal. There's a ledge up near the ceiling and a cube spawner on the other side of the room. I started loading the platform with cubes, then I used the cheat that gives you all the weapons from HL2. I threw a few grenades into the pile of cubes, and suddenly the cubes were falling like rain. "Oh no, it's the cubic apocalypse! Run for your -- wait a second that would be an awesome username!"

Burning97: was my old habbo name, my friend was blazingwater and at the age we were he thought anything ot do with fire was awesome and the 97 is my year of birth so it stuck

MonThaBiffy: The name I want my account changed to, it refers to my love of the scottish rock band Biffy Clyro and the crowd chant at their concerts "Mon The Biff!" "mon" meaning "come on" in scotland (where I come from) it is also my current xbox live gamertag, if you also have xbl feel free to add me just tell me your tpt username at the same time because I might think you are a randomer

Eh, Guardian. I saw the movie 'The Guardian' and thought the name sounded cool. The movie was good also.

My name was made up when I was playing a game that needed a 6 letter/number name so I choose some random ones and liked this one.
