gross vulgarity in children's movies

For example, in ET, the little boy calls another kid penis breath.  What the FUCK.  How would a kid's breath smell like a penis?  I can't remember if it was Drew Barrymore who had penis breath, but she might have in real life anyway so maybe it was an ad lib and they kept it.

Apparently at the end of Teen Wolf there is a dude jacking off in the crowd.
