Aw, Greenhaus, you're just showing off!
You're right, of course. I guess the People Who Make The Labels wanted to chose a word for objectionable things that might include more than just sex.

And as long as we're talking about these things, I'd like to make an observation. Has anybody else noticed how so many recent movies have graphic depictions of vomit? Is that what we've come to? Sex and violence are no longer politically correct, so now we have vomit in movies. Well, the whole thing makes me gag.
