Your son and his father are playing picnic basket orb.?


if he says something about his dad, similar to called his dad garbage, then you should step surrounded by. but if he was just pouting, then thats what conventional 9 year olds would do. let the dad handle it.
I don't imagine it's a big deal. He was expressing emotion surrounded by a way that a normal 9 year old would. I've see grown men act much worse in a game of basketball if they didn't procure their way.
Not a big deal!
it's a game!
It doesn't seem resembling a big deal to me. He's just reacting to a missed shot similar to a normal 9 year old would. If he'd said something like "You're garbage" to dad, afterwards that would be something differant...
I don't see the problem with what you described."That's garbage!" is not "God dammit!" or "f**k!".

He'd have to win over it and learn that he won't always make the shot.
I do believe a lesson in sportsmanship is in order.
Not a punishment or consequence, simply a lesson.
Sit..talk...discuss..communicate.
I agree with bjoy

Sometimes I let my kids get away beside things and then later when we are alone we talk going on for it and why I felt their actions were wrong instead of making an issue out of it within front of everyone.
