This study analyzed the impact of the social media platform X on the linguistic behavior of adolescents. The study emphasized the important role of the digital context in encouraging linguistic creativity and innovation. This study used a descriptive approach as a research method to analyze 30 examples of English slang expressions that were deliberately selected. The findings showed that adolescents were actively involved in the use of slang in social media interactions. This linguistic adaptation was achieved through the modification of existing terms or the creation of new terms. Rapid dissemination, cross-platform adaptation, and specific usage were influenced by peer networks and viral trends. These findings highlighted the role of X as a driver of linguistic evolution, with implications for educators and linguists studying contemporary language change. Further research could have expanded the sample size or explored cross-cultural variations in the use of digital slang.
