One Bounce Butt or One Bounce Booty.

When a girl has the most perfect bubble butt possible, where whenever she takes a step, her ass bounces once only, up and down. An OBB is the perfection of a perfectly sculpted ass.

Commonly referred to when a girl wears spandex, leggings or other tight fitting clothes.
Damn! That ass is perfect!

Yea man, that is defiantly an OBB right there.
