When you are banging a girl in a car and she accidentally, or purposefully, touches the honk with her impressively sized bottom resulting in a long (or rythmic) honk.
- Did you hear that?
- Yeah man, Jerry be banging that wide-ass Lakeisha chick. That was probably her ba-donka-honk.
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).
