That's why I'm having trouble understanding why you find it so difficult to believe he meant anything else (other than a female body part reference - who came up with that silly "hormonal reference," anyway?). Throughout his entire history of publicly disrespecting people, he's never done so in such a veiled and non-specific, open-to-interpretation manner. Plus, the narrative you're giving us here is that he disrespected Rosie O'Donnell, but you're either leaving out of forgetting that his 'disrespect' was a direct response to where she started it, by publicly criticizing and mocking him on The View. Prior to that he had never said a disparaging word about O'Donnell. But his response wasn't a veiled metaphor open to interpretation, he didn't mince words by calling her a "whatever," he just straight-up called her a "big fat pig."
He rarely attacks anyone until they've attacked him first. And when responds, he's purposefully blunt, to be shocking. "Whatever" is hardly blunt. So, given his history of "disrespecting" people, and the manner in which he "disrespects" them. why on Earth would you even think he mean it as a female body part reference in the first place, much less why you can't believe he didn't meant in in that manner? There's simply no foundation to believe that he meant it in some sexist, female body part way.
