a person with a big fat butt that looks like it was dipped in butter and fried in a deep fryer
My cousin’s butt is a kadunkadunk. It could bench press a donut.
I asked her if she was a kadunkadunk, and she said, ‘I’m a full-time kadunkadunk.’
She walks in, and the whole room goes, ‘Oh my god, that’s a kadunkadunk.’
