Shake Your Booty

So, we were driving home from the park the other day and the song Shake your Booty came on and it is Mikelle's new favorite song.  She was dancing to it in her carseat, trying to shake as much as possible while in her restraining straps.  Anyway, it was so cute, I didn't even know she knew what a booty was, or how she learned it, but I asked her "What's a booty Mikelle?"  and she said "A booty is your bum, mom" while pointing one finger to her bum.  How do kids pick up on these things, she is with me all the time, and it is not like they sing this song on Barney.  So she asks to hear the song all the time and she sings it so cute, it is also really cute to see her really trying hard to seriously shake her booty.
