Well, a "PG 13" is kinda like, in between a "PG" and an "R," or it's got slightly more subject matter than PG,ie laguage maybe some partial nudity(butts is some cases) more suggestive or sexual dialoge, more violence, and things like that. But nowadays, they are even pushing the boundaries of what is considerd "PG 13." They seem to be saying "fuck" alot more often in PG 13 rated movies at least once or twice. And some of them even seem more "R" than "PG 13" and vice versa. Things are changing and shifting now, and pretty soon we'll have to rethink what we view as an "R" or "PG 13" movie.
