A woman's rear end which happens to be so big that when she walks and extends her right leg, her left butt-cheek bounces off the ground creating a sound similar to "badonk" and is then followed by a louder "adonk" when left leg extends and gives way to the right butt-cheek.
As the woman strolled down the street one could hear "badonk.. .adonk.. .badonk.. .adonk. ..badonkadonk."
