I think profanity is in the ear of the beholder. There are many words that I would think profane if said in front of someone my mother's age, in the presence of a child or in a church etc..

...but in the privacy of my own home, with others of my peer group (whom I know to be of similar thinking) or in books or movies, these same words might be perfectly acceptable.

Newfoundlanders are the only people in heaven who want to go home.
