A badonkadonk gone horribly wrong. Usually found on obese people, or if one has an extremely saggy fat ass. You may see potential in a ba-chunk-a-chunk to become a badonkadonk with a but lift/serious weight loss, but usually one cannot salvage any bodonkadonkness in a ba-chunk-a-chunk.
Thank god Kirstie Alley got rid of her ba-chunk-a-chunk, not quite a badonkadonk yet, but she'll get there.
