Flat chest

(1) a female's upper torso with no or little curvature, having no or very small breasts;
(2) a female with such a chest, or more regularly, who is thought to have a flat chest, but actually just has A or B cups.
Usually meant as an insult or self-deprecating remark, but reclaimed by some as a source of pride and self-worth.

- "I can't believe Yuri's dating that flat chest from art class."
- "Aww, shut up. First of all, she's a beaut, and second, those are definitely B cups."
