Amazon sells badonkadonk. Which is, apparently, some kind of Burning-Man-related vehicle from a conceptual design firm. Now, of course, since they’re made-to-order, it’s not likely that more than one was ever built. It’s possible none were ever built.
My current guess is that this personal tank is named after the booty, and not the other way around. I have no etymology for the booty, though. Oh well.
