When I was around 10 years old, while playing FF9 for the first time, my friend asked me what Inertia was so I sang him a song:
"Oh Inertia, some people call you Joe. Oh Inertia, you are a violent hoe!"
A little while later I needed a Starcraft user name. I recalled the incident, and being 10, I didn't know how to spell Inertia so I guess. And the name just stuck, I use it for everything because its never taken.
LOL
