follow me into the rain

I think I would put "PG-13" on them... maybe PG if it was just "goddamn."

I think "crap" and "hell" and "damn" are the more PG swears. "Ass" is PG too, I think, but "asshole" is PG-13 (weird I know). Something about "ass" still being reference to a donkey, while "asshole" definitely isn't. "Bitch" and "son of a bitch" are PG-13... though I think a lot of people will say "cunt" is automatically an R, it seems to be quite a nasty word to many people (I think that's a North American thing more than a UK thing, though). I personally don't have much issue with it, though I don't really use it or hear it much either.
