No you di'int

Yesterday my daughter was responding to a story I told about her dad facing off with a raccoon. Princess acted out the racoon's role personified as a girl waving her finger and bobbing her head saying "no you di'int". The only description I can come up with her role playing is the stereotypical one of a black woman in the beauty salon talking with her friends and making the same exaggerated expression.

So my questions are a) how did my daughter do that with such precision b) where did she learn that expression and c) how did she know that that would be the perfect thing a raccoon would say when confronted by my husband with a broom. I'm thinking Hannah Montana had something to do with it.
