This MAY indeed have been discussed before BUT... SPOILERS and several sensitive subjects WARNING...

Why does Myra Breckinridge's character perform that forceful act of strap on rear penetration/assault act against that young man, what was her motive for doing so? Why did she want to humiliate and hurt him this badly? Also, did it not remotely scare her that he might say report her to the police for it or exact vengeance?

And also, based on that act alone, besides being wrong and criminally offensive of course, would you say that makes her an evil villain in this movie and very much the main antagonist?

And did the filmmakers here try to say something in particular with that scene, thanks.
