This study examines a compelling linguistic phenomenon within the social and political spheres: the use of dark humor—specifically, identifying the forms and meanings of harsh expressions (sarcasm) employed by Kiki Saputri. The research addresses the following issues: (1) the forms of dark humor used by Kiki Saputri in Episode 14 of Kaesang Pangarep’s YouTube channel; (2) the meanings conveyed through these dark humor expressions; and (3) the relevance of the findings to Indonesian language education. A descriptive method with a stylistic approach was employed. The data consisted of Kiki Saputri’s utterances containing dark humor on Kaesang Pangarep’s YouTube channel. Data were gathered using documentation, listening, and note-taking techniques, and subsequently analyzed using linguistic theory through the steps of identification, classification, interpretation of meaning, and conclusion drawing. The results reveal three primary forms of dark humor used by Kiki Saputri: sarcasm, irony, and cynicism. Sarcasm was the most dominant form, accounting for 33 instances in the data. These stylistic devices serve to create comedic effects, convey social and political criticism, and raise audience awareness regarding sensitive issues such as political dynasties, social inequality, and the behavior of political elites. The meanings conveyed include mockery, innuendo, and criticism. Regarding its relevance to Indonesian language education, the study offers insights into teaching stylistic devices, figures of speech, and meaning analysis within the context of humorous texts and social commentary.
