"If a man were to brush my ribs and does not stop when asked, I will happily give him some broken ribs."
Men who know how to behave would never even think of "brushing your ribs" or brushing the lower end of the dorsal side of your torso. (It's too bad Civil Comments disapproves of a simple three letter word).
But, maybe if more women tried your approach, there would be fewer men who don't know how to behave.
