Honestly, I would say something to your manager. I would try and step away and not get personal about it, refer along the lines of "the attitude is deamining to other developers" and "can harm retention and acquisition of new talent". I was recently in a similar situation where anyone disagreeing with the "golden boy" was chided by him. He's just another bully, generally when you stand up they leave you alone. I had a word with my bosses boss and my boss at the same time, said basically I have thick skin, but at the end of the day his behaviour is pissing me off, something needs to be done because if a Jr was being "coached" they would likely freak out due to the condescending manner. Good luck!
