If you listen very closely, you can hear her mom whispering at the beginning of the video, "Stop talking about balls."
This only forces Julia to clarify that she was talking about things like bouncy balls, before realizing she might as well start whispering "hairy balls" since they're on the subject. To her mom's horror and delight, she proceeds to wink into the camera seven or eight times in a row with each eye before saying, "Call me."
Julia's pretty cool with the fame.
Kids these days.
