i don't use curse word cause there are word that can hurt someone 100 time worse than saying "fu" i curse a lot when i hang out with friend, it really show how close two person are when one can curse out loud and the other is not offended
What about changing "MOTHER F****ER" into MOTHER FATHER?? It's more polite. Even it cant express your anger. LOL
I dont know which kind of enjoyment you feel but its gonna create problem for you some day. so better not to use this word. having a clean language is not a bad thing.
