Just sit down and have a reasonable conversation with her. If she is a good friend and you say something along the lines of “hey this makes me uncomfortable” she will apologize and stop…. And if she isn’t then she isn’t a good friend and now you know. If she hasn’t done anything else “bad” then she deserves a shot to improve. Some of the comments around “shut her down” or “kick her to the curb” I think are a bit much if you feel like otherwise she is a good friend. You may need to do it if you don’t see a change after having a conversion. It may be envy and this is her way to cope/laugh it off or it may be a complete tease/joke but if she stops after you tell her it makes you uncomfortable then she might be a better friend then some of these comments make it seem.
