This sounds all too familiar. I once had a Captain screaming at me when I made a small mistake on a radio call. I had already rectified it (I called we were climbing to FL 50 not Alt 5000') as I noticed it as it came out my mouth, but he was already screaming that about it.
ATC even asked if it was Ops normal as they could hear him in the background I told them to stand by, let go of the PTT and told him if he ever spoke to me like that again he'd be unconcious for the rest of the flight.
He was as nice as pie after that! Oh did I mention that it happened whilst I was line training!
Anyway, these idiots do exist and all you can do is to be as professional as possible. Mention to the CP/Fleet manager, talk to other F/O's as if there are a few of you saying the same thing, they are more likely to take notice. Difficult in a small organisation sometimes however.
Good luck with this pratt and when you get the left seat remember him and be nice!
