This study explores how "brainrot memes"—a genre of online content characterized by chaotic humor, surreal audio-visuals, and nonsensical language—are reshaping the cultural expressions and linguistic habits of the younger digital generation. Drawing on discourse analysis and semiotic theory, this research investigates memes function that are not only as entertainment but also as tools of identity performance, social bonding, and language innovation. Through an analysis of their form, context, and audience reception, the study reveals brainrot memes challenge conventional communication norms, foster new internet dialects, and reflect a broader shift toward irony-driven digital subcultures. Ultimately, the paper positions brainrot memes as both a symptom and a shaping force of how Gen Z and Gen Alpha relate to meaning, emotion, and expression in the algorithmic age.
