I used to work with a guy that was one of those body builder muscle heads.
He would have been a great bully if anyone let him.
I met him about my second day on the job, and he tried all that 'puff up and look bad' with me.
I told him, "Dude, you're too big to whup. I hope I don't have to shoot you".
We got along great after that and traded insults & 'zingers' for the 11 years I was there.
