I suppose you could have gone over and tried to be reasonable. Just say something like, "Dude everyone on these courts can hear you screaming obscenities on virtually every point. Please tone it down. If you have to, just mutter something like ****, ****, or balls under your breathe when you make an error. Why do you feel the need to scream at the top of your lungs? It's not going to help your play and it makes you look like an ***. Just have fun and play the ****ing game."
