Mine is SpotlessStar.
It all started in January of 2011. I had started playing chess, so my dad showed me this cool site chesskid.com(which is a mini version of here). And I saw this username on the list. I decided at the time that it sounded great, eventhough I am not spotless, or a star is not "spotless" it sdounded like a good name, and now I take it to mean a Spotless chess Star. Also, in Italian SpotlessStar is ImmacolataStella, eventhough stella is not my real name.
 
     
     
     
     
     
      
Where did your username originate? There are many unique, odd, or even downright ludicrous usernames on this site. Some have an obvious reason, some are chess-related, some are personal, some look like they were created when the user faceplanted into his keyboard, and et cetera. Shall we discuss where ours originated? I'll start.
My username, camberfoil, is a combination of the words camber, and foil, short for airfoil. Camber refers to the asymmetry of the upper and lower halves of a plane's airfoil (that's where the foil part comes in). This asymmetry creates a differential in pressure over and below the wing as the aircraft accelerates. Once the speed is sufficient, the pressure differential will grow enough so that the wing is drawn to the area of low pressure, above it, pulling the wing upwards, producing lift. It is, in essence, how a plane flies. Plus I just like saying camber over and over again. Camber. CAM-BER. Camber. Cam-BER. CAM-ber. Caaaaammmm-berrrrrrr. I think I've gone off the deep end.
