The wonderfully arousing patch of chest hair running along a male's sternum area. It is a known aphrodesiac for women. It is normally presented in the male's courtship/mating rituals by leaving the top couple of shirt buttons undone. It effectively shows the male's superior levels of testosterone, strength, masculinity and mating desirability.

sternum chopping is the action defined by approching members of either gender, and chopping then with the side of your hand, directly on the sternum. emotions expressed by sternum chops range from love, to anger, based on pressure applied to the sternum. if the person you are doing it to, is rather buxom, you may call it "cleavage cut"
she came right up to me, and sternum chopped me really hard. I think she was mad.
