badonka donk is when you've got a girl, her legs are on the mantel, and you scream skank'D into her nose. No really. It is. i saw it on TV once. Honestly. BADONKA DONK!
Big 'ol ghetto booty; a booty that when you look at it, it makes you bite your bottom lip; a booty that you could sit your drank on at it passed by you in the club and she wouldn't even know that it was there
