Bad Onion 

Anyone that gives a great blow job, but leaves you with stank dick afterwords (especially if they ate onions beforehand).

Man I was so excited when she offered to give me a bj, but she just turned out to be a bad onion, I could smell my own dick all the way into the shower!

Ba-donion 

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.

Oh word, look at that Ba-donion!!

Yo pimpin, I would wear out that Ba-donion!!
