a female that has an ass that looks like 2 basketballs are stuffed into the back of her pants.
Azalea down at HOME DEPOT sure has got basketball booty.
When playing basketball, they way someone sticks out their booty really exaggerated when dribbling, in triple threat, or about to shoot. Their back is arched backwards too far and their knees are low and wide apart. Looks like they're about to booty dance. Mostly, and hopefully, found in females.
