Well, since Bucks and Blues and I are both from Texas, I can tell you how we'd handle it.
You take her behind the wood shed, you push her up against the wall, and you tell that hussy if you even so much as hear a peep out of her mouth again, you'll beat the living snot out of her. Or you can tell her you're fixing to sue her for defamation of character, and that you'll bring witnesses in, and that you'll own her by the time you get through with her. If she's married, get your hubby to talk to her hubby - that usually stirs the pot.
Or you can simply ignore it. Women like that, no matter what you say or do it makes it worse.
I don't know, I know when I finally get to the face-to-face thing, I've got so much pent up feelings, that I have to remember that they have to swing first - once they swing first, it's open season.
Got into sort of a situation like that... a lot of us parents wanted to keep our athletic director, the in-bred ones didn't - and it all came to a head at a danged track meet in the concession stand that me and two friends were working at. One of 'em was stupid enough to say something snotty to our faces, and Lordy I came unglued. I didn't touch her, but Lordy it took everything I had not to - they kind of backed down after that.
Just don't end up in jail over it! HA!
