That's rolling on the floor, laughing at Mollie. Let me explain.
We have been trying to get Mollie to eat more protein lately; we usually tell her that protein will help her grow stronger.
So yesterday, she asked me for some cheese to help her grow and to "kick butt on ass." Yes, you read that correctly and I almost spit tea out of my nostrils! I think she meant kick butt on cancer. Sometimes Matt says she's kicking ass on cancer... hence the confusion.
I am still chuckling about it.
