Fladdies

The smallest size of a breast. Fladdy owners are usually completely flat chested or have breasts the size of a small fruit. These small-fruit size breasts are a subset of Fladdies, known as Apple-fladdies. Another subset of fladdies are Sharp-fladdies, which usually have perkier or larger nipples.

Person 1: Yo, those fladdies are sick!
Person 2: Those are Apple-fladdies, idiot. You aren't cultured enough to enjoy REAL fladdies.
