The night Donald Trump literally stalked Hillary Clinton onstage made her skin crawl. This is just one revelation in an excerpt from her new book 'What Happened', written and narrated by the 2016 presidential candidate who experienced a stunning loss to Donald Trump.

The second match-up between the two candidates was hyper-charged. The Oct. 10, 2016 debate took place days after the release of Trump's 'Access Hollywood' tape in which Trump bragged to host Billy Bush about grabbing women “by the pus*y.” The video threatened to derail Trump’s White House race as Republicans sought to distance themselves from their Republican standard-bearer.

Trump pulled out all the punches in the following days, becoming what his supporter former Brit politician called a silverback gorilla. Watching the debate, I found Trump's looming, hulking stalking of Hillary on the stage, making sure that he appeared in all her photos looming behind her in a dominant position, visually intimidating. Couldn't she have one photo of her answering a question from the audience without his awful bulk towering over her. Trump was communicating the same unsettling danger associated with his personality at that debate.

The event began late because Trump hosted a press conference with Kathleen Willey, Juanita Broaddrick, and Paula Jones, all of whom accused Bill Clinton of inappropriate sexual behavior. Trump -- who has an endless string of marital infidelity and countless women in his life -- argued with debate officials over his demand that the women be seated as members of his family, where Hillary would be faced with them in the front row. Debate officials refused, but Trump was willing to delay the debate start over this issue.

In the audio reflection shared today on MSNBC's 'Morning Joe', Hillary Clinton reflects on that night.

“I chose option A. I kept my cool, aided by a lifetime of dealing with difficult men trying to throw me off,” she writes about Trump stalking her around the stage. “I did, however, grip the microphone extra hard.”

“I wonder though whether I should have chosen option B,” she continues. “It certainly would have been better TV. Maybe I have over-learned the lesson of staying calm, biting my tongue, digging my fingernails into a clinched fist, smiling all the while, determined to present a composed face to the world.”

Trump's stalking performance inspired a “Saturday Night Live” parody with Alec Baldwin’s Trump following Kate McKinnon’s Hillary Clinton around the stage with the theme of 'Jaws' playing in the background.

Indeed A Silverback!

Looking at the image of Trump in our Oct. 11, 2016 post just now, I'm even more spooked. Trump's fingers are resting on his belt, unlike the image above. That is not a common gesture, unless it's a macho one of a man not only invading her space but resting his fingers on his belt buckle to outline his assets, write body language experts. An example:

Thumbs in belt or pockets

The thumbs are hooked to the belt or the pockets while the fingers spread out and highlight the crotch. This gesture is used by men to display a dominant, sexually aggressive attitude. It's perhaps the most direct sexual display a man can make towards a woman.

Men also use this gesture to stake their territory or to show other men that they're not afraid. This gesture communicates the non-verbal message, “I am virile, powerful and dominant”.

I swear to the goddesses that what follows in PsychMechanics is just part of the flow. My first stab at codifying the body language, because I really didn't notice the hands on belt buckle in Oct. 2016.

Interestingly, this crotch display gesture is also seen in apes and some other primates. Even though the apes don’t wear any belt or trousers, still they highlight their crotch with their hands when they have to stake their territory and show other apes that they're unafraid.

Some primates such as baboons are a bit more direct. They display dominance by spreading their legs and displaying their penis, giving it continual adjustment or even waving it at their enemies.

What’s even more mind-boggling is that the same penis-waving tactic is also employed by some New Guinea tribes even today who are essentially cut off from modern civilization.

This clearly indicates that such a behavior is an evolved tendency in homo sapiens.

Does Trump have a penis problem?

Writing after the debate, I did ask this question, but it was more within the context of my personal suspicion that Trump actually has a very normal penis or perhaps even one smaller than average. I know of two very tall men who were close friends of mine for years. Both men are highly successful -- one a captain of industry in Europe -- and they are not the least bit obnoxious, as Trump is. They adjusted to their small penises quite brilliantly.

My suspicions of Trump is that he is not at all endowed, which is more than this silverback gorilla can handle. To me, this has helped explain his absurd dominance over people. Writing for The Guardian, Carole Jahme backed up my suspicion. The silverback has the smallest penis of all and relies on his strength and girth to dominate female gorillas.

What's more, Hillary is a bonobo, the smallest among apes and also part of a matriarchal social organization. Indeed, bonobos rule! Bonobos are also the smartest members of the ape family, leaving silverbacks in the dust. And I don't know how to break it to Trump and his buddy Nigel Farage, but male bonobos -- while small and pussy-whipped with endless sex -- have a penis larger than any silverback ape. So there, Donald! Hillary is right, you were and are a truly CREEPY man! ~ Anne
