It is a limited vocabulary which means people cannot express themselves so substitute with swear words.
Other people use swear words as an expression of anger and annoyance.
But there is always a time and place for that.
Sass? you can make sense, I agree with you, but the world changes as time goes by and swearing is no longer frowned on by our newer generation and when you think about it they are only words, I still don't like to see or hear them, after the third swear word here in my home, I start to think about if I want this person here or not.
I still don't expect anyone to exclaim 'oh what a nuisance I've hit my thumb with a hammer', so as you say Sass there's a time and place.
