BAD WORDS!

I think that "bad" words are considered on how you say them and the intentions behind them. Using bad words may get you're point across better because people may get surprised at your language and take you more seriously. Same goes for "good" words, I guess it just depends on the type of audience you're talking to and what point you want to get across. An appropriate usage of euphemism is when you want to get a point across but don't want to be too straight forward or sound rude. It has a limit to when it's appropriate and then to when it's just plain out being rude.
