The present study aimed at investigating the effect which the internet is making on the language, the discourse and the writing style of Iranian male teenager students in cyberspaces of Telegram and Soroush. To conduct the research project, initially, 60 junior high school students from SAMPAD, Rasht, at the ages of 13-15 years old were selected through non-probability convenience sampling joined in a common group on the social media as the members. Then, 837 utterances from students Netspeak were selected through purposeful sampling. Their social and verbal behaviors including written and spoken had been recorded and transcribed for one month. To this end, the data were analyzed into two levels of description and explanation. At the level of description, the features of network discourse inspired by Crystal (2004) were represented. Along with Crystal's classifications, this study achieved to other features peculiar to Persian networks as follows: Substitution for Persian alphabetic system (Finglish), lexical barrowing, text spoken style, spelling mistakes (slip of the pen), humorously idiosyncratic Netspeak, permutation of Persian word ordering, encryption, and punctuation. At the explanation level, the network discourse which was inspired by Gricean (1975) model, revealed that the cooperative principles worked differently and the quantity maxim was flouted without any violation. But other three maxims were in line with the prominent characteristics of the cooperative strategies. The results manifested that cyberspace for the survival of communicative competence generated the virtual variety as marked written register of Persian language for social media purposes.
