I was a little kid still new to the Internet. My previous username on different websites would be cptprice, because I was a huge call of duty fan.
Then I had the sudden urge to be original. I have noticed that just about every other username was something like, "supersoldierkiller," or 'xX_Swag_Sniper_Wolf_Xx', or, 'narutofan134646597', and etc.
So I came up with Dudeman162, thinking it was original.
The end.
