This study aims to describe the morphological forms of slang, explain the processes of its formation, and analyze its frequency and distribution in the TikTok content of the account @shadirafirdausi. The study is motivated by the rapid development of slang on social media, particularly TikTok, as a platform where young people express identity, creativity, and social interaction. A qualitative descriptive method was employed using documentation techniques on three TikTok videos, including captions and comments with the highest numbers of views and likes during June–August 2025. Data were analyzed using the interactive model of Miles and Huberman, consisting of data reduction, data display, and conclusion drawing. The findings identified 36 slang words and phrases classified into four morphological processes: phonological modification (30.6%), shortening (30.6%), affixation (25.0%), and compounding with foreign element adoption (13.9%). Phonological modification and shortening were the dominant processes, while affixation and English borrowings further enriched the language forms. These findings demonstrate that slang in @shadirafirdausi’s TikTok content is formed through creative, productive, and adaptive morphological processes that reflect the preference of young speakers for concise, expressive, and easily understood language in digital communication.
