A PG-13 group may go beyond the PG rating in theme, violence, nudity, sensuality, language, adult activities or other elements, but does not reach the restricted R category. The theme of the group by itself will not result in a rating greater than PG-13, although depictions of activities related to a mature theme may result in a restricted rating for the group. Any drug use will initially require at least a PG-13 rating. More than brief nudity will require at least a PG-13 rating, but such nudity in a PG-13 rated group generally will not be sexually oriented. There may be depictions of violence in a PG-13 group, but generally not both realistic and extreme or persistent violence. A group’s single use of one of the harsher sexually-derived words, though only as an expletive, initially requires at least a PG-13 rating. More than one such expletive requires an R rating, as must even one of those words used in a sexual context.
