Main theme of this final paper is to study the non-verbal communication of American street gangs and to look at them through the prism of communication science. The paper deals with the general concept of communication, how and why we communicate. Throughout the paper analyse various factors that are essential for successful communication, the factors that make communication difficult and the factors that contribute to better, faster and more effective way of communication. Also, non-verbal communication is a big part of every person's communication habits, and communication is inevitably a daily occurrence for everyone, so we are also analysing non-verbal communication in this paper. Communication does not only convey messages, but ideas, opinions, and often in the course of communication the personality of the communicator is also conveyed, and the person receiving the message simultaneously learns how to communicate or copy the communication style of the person sending the message. It is in this case that we study the non-verbal communication of American street gangs, which over time have developed very specific and different communication forms, specially non-verbal ones. Due to the marginalization of American street gangs, and often illegal acts, this topic has become extremely interesting to pop culture. Various media platforms, music genres and popular people have adopted street gang style of communication and have directly started using the communication of a particular street gang for the purpose of promoting a "wild" or "more fun" lifestyle. Pop culture representatives have a direct and powerful influence on the youth population, resulting in the fact that young people who are not directly in contact with American street gangs adopt communication styles and begin to use that type of non-verbal communication for their own communication needs, which can easily be characterized as negative impact of non-verbal communication by American street gangs on popular and youth culture.
