Well, "The Naut" is sort of a shorthand for astronaut and also the name of a character/costume I came up with. Pretty much it's a guy in and Italian suit that kinda has astronaut gear strewn here and there. Helmet, gloves, boots, pack, etc, etc. Now the 131 comes from another username zeroG131...oh the memories.
So many funny, extremely stupid, internet addicted memories...
Anywho, the whole reason ZeroG131 came into existence was because I was trying to create ZeroG13 as my Youtube username but since it was taken, I randomly picked ZeroG with a 131 on the end, though I was actually trying to pick 113. Turns out I actually find the number pretty cool.
I got banned on the Escapist for being stupid and made a new account here. Since I got tired of using the same username on alot of things and wanted to start off fresh, I decided to use TheNaut here. I just added the 131 for a bit of continuity.
I guess it means I like suits, space, and have found the number 131 interesting and easy to roll off the tongue.
