Аннотация:The article presents the results of content analysis of Internet communication of adolescents (younger and older teenage groups of students). The basis of the study was school chats of a certain content orientation, which made it possible to identify lexical categories that complement and transform stylistic means depending on the situation of communication. It is concluded that in the Russian-speaking youth society there is a general tendency towards a "toxic" saturated vocabulary of Internet communication, as well as particular (age and gender) characteristics of communicants.
