Win or lose, "annoying" is the definition of Diaz trash talking during fights, IMO. He is never only satisfied in get the victory like a sportsman, he needs to openly bully and disrespect his opponents.
So if he and his followers are annoyed by a decision loss that's the best of both words here.
It's funny, when Diaz tried to stand in the middle of the cage with Condit stuff like this happened:
No wonder he didn't want to stay there with Condit.
