Hi J., not sure if this would work in your situation but stranger things have happened. Try telling her you don't use those kinds of words and if she has to say them that she MUST go to her room to say them. Tell her it is only ok in that room. When she feels the urge or need or whatever to say it she'll go in her room, say it, and now that she's got your "approval" the word will lose its appeal. We tried this with my son when he was younger and wanted to "explore" certain body parts. In Home Depot, in the grocery store, etc. Our pediatrician told us it's normal and common and to not discourage it or make him feel bad about it but that it's not polite to do so in front of everyone else. Once we told him he "could" do that, he went up to his room a few times (quite embarrassing to know what he was up to and he was completely ok with it!)and then he stopped. It lost it's appeal, it's power, etc. Hope it helps. Maybe it isn't the best advice, but at least something to think about.
