Pervasive Language

So I’m watching TV, and a commercial comes on for the movie “Ides of March”. It’s rated R, for… “pervasive language”. What? pervasive language? Like what, English? Yeah, English is spoken damn near everywhere, so that’s pretty pervasive I guess, but how does that call for an R rating? Language is pervasive amongst kids under 17 too. Damn pervasive. Heck, almost all of them speak it. Sort of. Some of them even speak more than one. Sort of. Anyhow, I’m pretty sure most kids have heard a few different languages before they reach 17, so what’s the deal? Oh, wait… is “language” code for boobies?
