A nice piece of ass characterized by an upside down triangle of light formed by a fit womans crotch and thighs allowing light to show through. Usually means one won't be dissapointed

The view obtained when you look at a womans ass from behind while she is wearing tight pants. If you can see daylight through the crotch of them, she's not overweight.
