longback 

1. A term used to describe women who lack a definable posterior.
1a. A girl/woman with noassatall syndrome.
1b. The opposite of bootilicious.
1c. Lacking in the booty department. A person devoid of a sufficient amount of jelly in the booty, giving the appearance of their back extending further than it really does. Hence, longback.

I've seen black girls, latin girls, and even white girls that got that booty. But asian girls? They're mostly longbacks.
