So i can assume that you agree that chassidish means something.
Maybe.
I would guess that being Chassidic means being a member of a Chassidic sect. But then again, I (in my vast ignorance) could be grossly incorrect.
If I am incorrect and “chasidic” has no true meaning, then so be it. Feel free to say I’m chassidic. I may not self-identify that way, but I can’t stop you or anyone else from saying it.
