I think we all have been through that, and more than once.
When I was younger, I was helping to a stonemason and he had a little bit evil tongue. He was a very nervous guy and swore a lot. Each of his sentences contained at least two-three swears. Whenever something went wrong or if he (or me) made a tiny mistake, it was all followed by a river of curses. And those curses are not what you can hear every day, these were his original content. Like he was threatening to me once:
"Your mom will find your fucking tooth on a shelf in the damn butchery store!".
Or once when he broke the stone the way he didn't wanted, he openly threatened to the stone:
"I'll fuck your grandma with an eggplant and you'll have to watch it from the wheelchair!".
But while he drives, he swears everything and everyone! Pedestrians, other drivers, traffic lights... Once I was in the car with him and he was screaming because the car in front of us was too slow:
But my uncle is the best driver that I ever met.
Swears are taboo abut it seems that little children are really having fun using the. When they discover that new, funny words, they just don't stop to use them for a while.
Each language has it's own original swears and it is impossible to translate them on other languages, they lose it's meaning. When foreigners come to Croatia, many of them usually wish to learn some good, old, domestic swears.
We came to see what is happening and there were many words like "cunt", "cock", "suck" and "asshole", they mentioned God and all saints several times so we had to cover the ears of the kids because they absorb everything like sponges.
