That's nothing. Freshman year of college I was becoming fast friends with this girl. As is my nature, I like to tease my friends. This particular girl had very large breasts, and was sensitive about her weight (she wasn't overweight, but was convinced she was). She was complaining about how a certain shirt made her look like a man, and I said "with those breasts, pretty much the only man who looks like you would be a sumo wrestler." Now, I clearly meant that men don't have breasts unless they are appallingly fat. Guess how she took it?
Six years later, five of them happily together, and she still brings that up (along with a time I apparently called her an Orca, which I don't remember). "You look great hon!" "Yeah, for a sumo orca..." GAH!
But I learned well from her. You just reverse it. For a while, I took everything she said the worst possible way ("Want seconds on dinner?" "Oh, I'm so fat I'm obviously never full, is that it?"). A few months of that will make a woman realize just how obnoxious it can be to take everything as a negative and they'll cut back. I figure it's not healthy to take everything as an insult, so you're really doing them a favor.
