Madonna -- '#Nosausage' Quip Not Cool with Rocco

There are things that are universal ... little girls don't like their ponytails pulled, little boys don't like their cheeks pinched, and teenagers don't like their moms talking about their sausages.

Everyone involved is tight lipped about the rift between Madonna and her 15-year-old son Rocco, but it doesn't take a rocket scientist to know that it's uncool for a mother to post a video of her son doing a backflip in his boxer/briefs with the caption #nosausage.
