Offensive word

A word that I personally find offensive that others may use casually is cuss word. I don't like cuss words, any of the cuss words because to me cuss word is for the people that don't have good humor and they are from very lower education. For example I don't really think that a well educated person (teacher) would yell at you with using bad word in front of people. I don't cuss at people even when I am really mad.
