steavage

The lower portion of a woman's cleavage. Named for the visibility of a woman's sternum while wearing a revealing garment.

Ian: Oh man, you should have seen Jane's shirt today, total steavage.
Alex: What's steavage?
Duncan: It's when the cleavage goes so low you can see the girl's bra wire or sternum.
