The mix between a Badunkadunk and an Onion. Both of which symbolize a girl with a nice thick ass that would make a grown man cry (onion). The beauty of the word Ba-donion is that you can say it and not sound all stupid and trendy like the d-bags that can't come up with their own original sh!t.
A layer of buttery cheese commonly found on a sorostitute's back, just above her waist that usually shows signs of dunlap disease and may or may not be accompanied by a large stripper tattoo.

Damn, that sorostitute has a serious case of the fatback!!
