One form of language I can't stand is the 'chav language'.
Almost every word they say involves violence, drugs, 'bling bling' or other adult things.
They also swear alot, even at elderly people.
But on the subject of swearing in general, mild curses are fine like 'darn it' and 'hell'....but using strong language such as the f word or b word is not necassary.
