Okay, it looks like I got this wrong. I looked everywhere this morning for some description of what he was doing, and I was unsuccessful. So I went with widespread Twitter sentiment.
"Should I do it? I'm gonna do it!"
And that's when Trump apparently mimed dropping his drawers to make a doody, complete with grunts.
No, I don't know why, and I can't think of one good reason. What I know is that a former president of the United States and a current presidential candidate did whatever this is on stage to amuse his cult members.
Noel Casler, who worked on Celebrity Apprentice, reminds us often that Trump wears adult diapers.
However, this tweet has since been brought to my attention:
Brian Krassenstein says he was pretending to be a female weightlifter. My apologies to you all, I still think he looks like he's working out on his golden throne!
