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.

Get the ba-chunk-a-chunkmug. Verb: to be actively fat. Not limited to a lifestyle of eating fatty foods or not exercising, but instead the entire state of being a fat person.
I am chunking so hard lately - I ate 2 double cheeseburgers for lunch this weekend and that was totally normal for me.
