Put it away, and for God's sake, turn the damn thing off in class. If I were the teacher, I would dock ten points from your final grade for every ring I heard. And I'd be laughing all the way home. It has no more power than you give it, and little or no intrinsic worth. It is nothing more than the passing of air over the vocal chords in a certain way, combined with shaping the mouth in a certain way to form the proper sounds.
People speak all the time about bad words.
There are no bad words, people, only bad thoughts. Sometimes, a swear word is the only word that will properly convey the desired emotion. For example, in my bedroom, I have a poster with a photo of the Hindenburg blowing up all over the place. I cannot think of a better use for this word, because I can just see some guy standing down on the ground watching this huge fireball, and you just know that that's what he's thinking. Secondly, I alluded to this up when I was talking about bands misspelling their names, but it applies throughout life.
