An ass, generally in reference to a woman, that lacks curvature or "junk in the trunk." The ass is very flat much like that of an elephant in appearance.
That girl has the flattest ass ever, she is suffering from a severe case of elephant ass.
Simply put, it's when the ass eats the pants. Usually happens when there is excess space in the seat of the pant, thus causing some fabric to be pulled inward into the colon area.
Dude, did you see that old guy in the khaki's? He had major elephant ass!
