There's a noise that fangirls of pop-bands and various fandoms
   make. Fangirls are not limited to girls.

   The word is "squeeeee!" and is accompanied by pulling your arms
   together in front of you, almost applauding like a seal and
   smiling and maybe jumping up and down.

   Railguns give me that same kind of squee feeling, although I
   restrain it. I actually hate most guns in general, but railguns
   are EM. and I love pure EM stuff. Squeeee!
