I interpreted your post a different way and you can correct me if I'm wrong. Does your friend actually have OCD or is she just terming certain actions in a matter of fact way and that's what's bothering you? Or does she have it and is blaming it or using it as a crutch?

Is it using the term loosely when she doesn't have it that bothers you? If that's the case I could see how it's not right.
