OC stands for "Original Character" or "Original Creation", so yes, anything fan-made.

I would say Reihana Uzumaki is OP, even though there isn't much info about them at this time. There are some characters like that on this site, however, we try to help people avoid that with critiques. Other sites like Naruto Fanon have way worse. I don't think I've ever seen a character on there that wasn't some kind of OP monstrosity.
