This study explores self-deprecation within the context of Korean reality TV shows, examining its multifaceted functions, recipient responses, and interactional consequences. Through analysis of excerpts from two Korean TV shows, Infinite Challenge and I Am Solo, various uses of self-deprecation emerge: as a defense mechanism, self-blame tactic, means of reprimand, and even as an accusatory tool. The findings illustrate the complexity of acts with self-deprecation, diverging from previous studies where self-deprecation is the main action for all participants. Participants may overtly acknowledge self-deprecating actions, yet these actions can also be layered with other interactional goals such as defense, reprimand, or accusation. Consequently, misinterpretations of self-deprecation can lead to tension or unintended outcomes. This study underscores the contextual and contingent nature of self-deprecation, emphasizing its role as a dynamic "communication practice" (Speer, 2019) in human interaction. By delving into the intricate interplay between selfdeprecation and other interactional goals, this research contributes to a nuanced understanding of this phenomenon in social contexts.
