- Microboobs; a girl with tiny tits that are so small, they are almost non-existent.
- Breasts small enough to either be covered by a training bra or no bra at all.
Microboobs are generally the smallest of the small in tits. Some people love this sort of look, especially on a girl who is otherwise curvy or has a nicely built feminine body, while others are concerned that it plays to a more pedophile crowd. Generally the hottest microboobs girls have either larger, rounder butts or very sexy pussy areas. Also known as flat chested or as flatties
