An ‘ebonic’ expression for an extremely curvaceous female behind. Women who possess this feature usually have a small waist that violently explodes into a round and juicy posterior (e.g., 34c, 24, 38). Other characteristics would be moderately wide hips and a large amount of booty cleavage (i.e, depth of butt-crack).
