What does it mean when a man compares you to Harley Quinn?

I have not seen the movie, what is she like personality-wise?

My ex used to say he was a Joker and I was a perfect Harley Quinn. He liked that I think, because he didn’t like if I was too sweet and caring with him.

The other day I was told that by someone else. That reminded me of the words of my ex.

And why would anyone like that? From what I know she is a villain, right?
