"grab her pussy"
Even in the conversation, he himself expressed disbelief at the fact that women would let him do that to them. It's not like he's doing that and they try to push him away or get mad. He's shocked himself that they let him do it because he's a star. I'm sure a lot of famous guys/powerful guys have experienced that themselves. Women around them become extremely sexually submissive and would let them go way out of social boundaries with them even within the first few minutes of meeting. As a man, I have personally experienced it myself and it's a huge turn on to know that a girl would submit to me like that.
So to me, Trump's statement is really more about the fact that women are whores and would sexually submit to alpha men easily than it is a statement about how he's a creep.
