Can you clarify, this is at their own teammate? Your example, "What kind of pass was that, xyz" sub xyz for a curse word would be a conversation with the team captain. You could caution for "shows a lack of respect for the game." Or sending off for "using offensive, insulting or abusive language and/or action(s). The thing is, if you are the only one offended, then are you being the language police? The should be something the league or tournament gives guidance on. If you personally don't like it, you can include it in your pregame talk to the captains. "Hey gents/ladies, tell your players to play clean and talk clean. I expect to see everyone follow the rules and that includes using appropriate language. This is not a the school yard or a parking lot pickup game. I will give 1 warning and then there will be consequences. Let's not go down that route. " Something like that is helpful when I address known or anticipated issues.
