Used to describe classically shaped and sized women's breasts, that are neither too large nor too small, commonly quantified as 34C. When a classic, conical-shaped martini glass is placed over each, they fit perfectly inside, with no air space underneath, and no excess breast sticking out.

the horrid shape of women with love handles, a gut, and absolutely no ass; the opposite of the hourglass shape
I hate chicks with the martini glass shape. If I could put the fat in their midsection in their ass, this would be a perfect world.
