obviously there are as in any language!But what could be the use of them if you are a polite fellow? anyway bad words, I mean really bad, are in the slang of a language,not in the correct language.For ex. you can say in correct English: you silly fellow, you stupid fellow, you donkey…and so on, but if you say " son of a bitch" you enter in the slang. And more: what is terrible for english people may not be so terrible for italian or for spanish or chinese. AS you surely know, there are many deep difference in the psicology and use, of different people depending by their culture.
