I was talking about everyday conversation around the neighborhood...I only heard the ‘f’ word ONCE during my ten years in Tennessee. In Red Hampshire? DOZENS of times every day...
In some circles, the words are unacceptable, in others ordinary.
The terms have become far more common over the years, not just in music, film, and the written word, but in ordinary conversation.
After the '60s, I heard them a lot more, and from people who generally did not use the words before. Since rap and hip-hop the words have become all too commonplace and discourse has coarsened significantly.
