I'll tell ya where my name came from. (I don't care that this topic is old, I've been gone, I NEED to post here)
Neo - Meaning new
Calculus - A really awesome name for a type of math.
So I am NEW MATH! But I suck at math, so I have no idea why I chose it except to hide my identity when I first joined.
My other name, Skull, is a shortened version of Skull Man X, a totally bad ass character I made two years ago while I was studying abroad.
