bad words

I think what makes words bad are the way people think of certain words, they may think certain words as impolite or rude. Also, the way the words are being used or in what tones they say it in. Such as, someone who stubs their toe wouldn't say a 'good' word but a 'bad' word to expression how they feel. I think the use of 'good' and 'bad' words help express what a person is thinking & expand how they want to express a certain situation or mood. I think the use of euphemism would be appropriate to use when talking/approaching someone superior & I think it becomes confusing when used in certain tones.
