TOG stands for That One Guy, which in of itself is a reference to a point out in the real world where I was being a dick to some people and rather than tell them my name I said "Oh, I'm just that one guy."
The solid part was given to me after I had snuck into the same movie theater twice in one day to watch Hellboy and Kill Bill. Thus was born TOGSolid.
Just recently at PAX it was expanded to Doctor TOGSolid after I became my group's medic when they all caught concrud and I knew exactly what meds and how much to dope them up with so they could function, however Dr. TOGSolid is just too wordy. It did give me the inspiration to put together a Dr. McNinja cosplay though.
