No, I can't make fun of Trump's weird "put a point on it" hand gestures because I am an unrepentant and wholly irredeemable hand talker. Admittedly, there's something way more snotty about the way Trump does it, but I have absolutely had people lose focus on what I was saying while they stared at my hands like I'm trying to karate chop them. I talk like Tom Cruise's character in court during A Few Good Men and it's not always endearing.
But it is weird - like he's trying to squeeze a tiny fart out of his huge ass by pinching his fingers together upside down.
