the opposite of budunkadunk
it means you have a small ass
also seedinky badinkadink- u need a small dick to put in that ass
badunkadunk- any size dick would fit but a huge one is preferable
damn that gurl got a badinkadink, too bad its not a budunkadunk i would "dog" her all night.
A lucky chance occurrence, like when this new boy you have a crush on in the 6th grade emails you and asks you to go to a movie and signs off XOXO and you realize just then, he has a crush on you too. That's a kawinkidink!
