In a social group, especially adolescents, the community creates a social language to communicate with all the members in their daily communication. The created language is inherent in each member of the group because of their close relationship with each other. The language that people use also clearly reflects the cultural values that exist within the group. The use of vocabulary items in speaking to other people in daily intercourse reflects the culture of the speakers of that language. The usage of rude words in communication with other people is bad communication. Nowadays, the use of rude words by teenagers with their peers in daily conversation is a sign of a bad culture. Using rude words, especially in formal conversation is not polite; in addition, the speakers who use rude words can also cause a bad image of the nation or the environment where the speakers live.
