When something has reached the point of being so ridiculous that the words "ridiculous" and "preposterous" cannot begin to describe it, so they must be joined. May be used to describe the feminine behind area, since it sounds close to ba-donk-a-donk. Could be a cousin to ridicularity.
The muffin top isn't so bad, but paired with the aggresive thong biopsy it's ridunkerous.
