I will be the first one to admit that I have dropped the F-Bomb a few times in my younger years, and I paid the price. Now it seems to be second nature in everyday conversation with no one taking offense to it, but in the cinema world it's been snuck  into some of the PG movies. Out kids will hear if eventually, but there has to be a line drawn somewhere in the sand. I mean Family Guy is a cartoon, but it has parental warnings before it. If we were to list all the "naughty" words during a movie preview then I would fall asleep before the opening credits.

Those extra expletives you’re hearing at the multiplex these days aren’t just echoes. PG-13 movies, officially allowed one non-sexual F-word per script, are making increased use of that allotment — and more — as filmmakers work the rules in a world where R-rated comedies full of both male and female trash-talk have become a summertime staple.

Recent PG-13 examples include F-bomb reactions to Ryan Gosling’s abs in “Crazy Stupid Love,” Bryan Cranston’s boorish behavior in “Larry Crowne” and those rampaging robots in “Transformers: Dark of the Moon.
