Well, there's obscenity, and then there's obscenity.
Being from a more ruralified part of the United States, where people farm, and fish, and hunt - and the most sophisticated thing we do is to sell antiques to the tourists who come out here past Covington from Atlanta and beyond - we tend to have a more earthy view of life. Especially back in the older days, when sudden marriages were rather common, men chased their daughters' boyfriends shotgun in hand, and so forth.
I mean, even the youngin's see the bulls and cows, dogs and pigs doin' what animals do.
When you're that close to life and death, when you deal with situations where birth control was best described as a combination between a rapid exit and prayer, and when you done got caught with a girl in the hay barn the whole damn town knew about it, you develop a sense of humor.
And we got our jokes and stories as well, the ones you don't tell in the parlor, but out back away from the womens. And when you do tell them stories, or recall and recount just why you and Maw Maw got married in the first place, clinicalified terms like "penis" and such seem rather cold. I mean, that old joke about that feller who wouldn't sell his cow cause it had a twitchet like a woman, and the other feller says ah I can beat that, you should see my wife, she's got her a twitchet like a cow! I mean, that wouldn't rightly work with the v-word, now, would it?
Some words're like a comfortable pair of ol' boots that you wouldn't wear to church or in the house, but are mighty fine for a day wanderin' through the woods looking for scrapes and deer tracks.
But I'll agree with you there, sometimes we go to Atlanta, mostly to see the grandkids, and the language you hear in the music comin' out of these cars, the ones where the body's shot to hell and the rims are right shiny, and there's more power in the stereo than the engine? Them fellers talkin' a load of foulness over some clicky stuff made by a computer, makes you wonder how they were raised. There are times to be using words like that sure, but as a steady stream of commentary - like usin' a hammer to crack an egg.
As the Good Book says, "to everything there is a season". There is a time and a place for everything.
