When you are eating some real good food and you are gripping it so tight to the point where your thumb bust through it in order to get a better grip on the food.
Jamarcus: Aye what you eat for dinner last night?
Armond: I had some tacos and them shits was bussin!
Jake: The concrete is BUSSIN
Rebecca: You're mis-using 'bussin'
Jake: how do you use it than?...
Rebecca: When something tastes good, it's 'Bussin'; concrete is not food, nor should you eat it,
so you're misusing the word.
