Rick,

I have experienced the "Trash Mouthing" and though I believe that rising above the trash is the appropriate action, there is a breaking point that I will put my foot down.

Take a look at Defamation and Slander. Depending on your situation, and your tolerance level of the trash mouthing, you may want to investigate legal proceedings. A legal letter (no big investment on your part)sent to the offenders should get the message across.
