Discription of Events: Tailgating car in front of it, weaving in lane, whipped from behind me at an intersection to get around me. Then made a right on red at another light, pulled a u-turn there to catch the opposite green light and was able to get in front of the car he was tailgating. At the next light he gave a couple thumbs up out the window and held his phone out the window as if he was taking a selfish (imagine he was taking a pic of the car he tailgated). Weird as hell.
