daboink-aboink
like a badonkadonk, but with a rack so nice it could give a donkey a complex
My cousin's walk is so smooth, it's like a daboink-aboink in a velvet suit.
That girl walked by me and I swear my pants got a hard-on.
My mom said I was walking like a daboink-aboink, and I said I was just being fancy.
