When a female has a huge ass, i'm not talking about a weak, scrwany, undernourished anerexic ass, i'm talking about a big, fat, jiggly, round booty.
IT got it's name, by mimicking the sound an ass makes from a distance (when you check one go by, in slow motion, it goes, Badonk-a-donk).
Damn Yo, that quite possibly is the biggest ass i've ever seen, that's not just an ass, thats a badonkadonk, i want a piece of that.
