Might define what you mean by inappropriate..Helps to know what the boundaries are...This could be a George Carlin kind of exercise..."The whatever number of words you can't use on TV."
Couple words are socially unacceptable...Yes...But,then like when you get reared from behind by a pink Cadillac with an anti-cyclist nut cake, you just might get a little animated..
My view about profane words...Try to be polite, but prudenism can go too far to.
