This article presents a study on the use of Korean slang, particularly secondary slang, in the popular Korean TV show Running Man. The researcher applied Chapman's (1988) theory to distinguish and categorize the types of Korean slang used in the show, limiting the types of slang to only secondary slang and particularly applying the category of loan words based on Choo and Kwak's (2008) model. Using the descriptive method, the researcher classified slang expressions used in two episodes of Running Man and found that 312 secondary slang expressions were elicited. The study suggests that Running Man is a window to visualize the Korean language and helps foreign audiences learn the slang easily and memorably while having fun. This information can be useful for researchers who are interested in studying the use of slang in different languages and contexts. The findings of the study are beneficial for students, instructors, and researchers who want to understand the characteristics of Korean slang expressions, particularly loan words from the English language into Korean. The study also highlights the importance of authentic language use in entertainment media for language learners.
