I have no personal stories, but I guess he's just an unrepentant a-hole. There was a story about him taking a foul tip off his nether regions when he was with the Giants, and kneeing the trainer in the groin when he came over to help.

That's really the only concrete thing I know of. The rest of baseball's fanbases hitting him just seems to be a snowball thing. "It was once determined that we should not like this guy, so let's dislike him.
And of course he headbutted Michael Barrett's fist that one time.
It's funny that for a guy that's supposedly so hated by teammates, there are no stories reported in all these years except for a couple during his one year in San Francisco. He was with the Sox for eight full seasons yet no incidents were ever reported by former teammates after he left.
