Ba-donion
A messy combo of Badunkadunk and Onion. It’s like saying a girl’s butt is so big it could make a man cry, and also be used by brainless d-bags who just copy sh! t without thinking.
My cousin’s butt is a Ba-donion. I swear, it could make a man weep like a baby.
I called my teacher a Ba-donion. She gave me a D- for that.
My dog tried to eat my butt. I told him it was a Ba-donion.
