Princess Teacup (dancing in circles): "My butt!"
Me (trying to hide my laughter): "Ok. This needs to stop."
Princess Teacup (laughing maniacally): "My butt! My butt Daaeee!"
Me: "Listen love, you need to stop saying that. It isn't very nice. And it's rude."
Princess Teacup: "Rude?"
Me: "Yes baby. I know it's funny. But you can't keep saying it all the time."
Princess Teacup (walking away): "Ok booty face!"
