Some classmates and I were playing counter-strike during one of my computer classes in high-school and I realized I didn't have a suitable gaming name. My nickname in Spanish Class was Nico and had been my personal nickname for a while.
Nico was kinda boring, so I wanted it to be iNico!. I didn't realize I could just use a lower case i as the first exclamation point, so I just used another exclamation point. !Nico! still felt kinda boring and conventional, so I made it !Neko!. Knowing that Neko meant cat in japanese, I threw on another K for good measure so it would be more unique. Since then, I've been !Nekko!.
If I can't use exclamation points on a site or in a game, my name will be either Nekko_Chavez or Nekko_Suarez, keeping up with the spirit of my Spanish nickname.
