My crush called me his daughter?

So my crush called me his daughter today, and I'm not sure what that means. Recently he's started doing this kind of thing a lot, but this is the first time he's ever called me that.
He's started saying the whole, "I'm big and you're small, I'm dominant you're submissive." He'll also saying things like, "who's gonna stop me?" When I tell him I don't like something that he does. (Never anything really bad he just likes blowing vape clouds in my face)
What does all this mean?
