This study examines how the term “fashion baseball” functions as a discursive resource for constructing fan identity and organizing intragroup boundaries in an online baseball fan community. Focusing on the layered interactional structure of posts, comments, and replies, thise study analyzes how the meaning of “fashion baseball” is constructed and transformed through repeated interactions. Data were collected from the “Korean Baseball Town” board of MLBPARK using the keyword “fashion baseball fan.” A co-occurrence analysis centered on “fashion baseball” was conducted across four interactional layers: posts and, first, second, and third-level comments. The findings showed that discourse develops in a layered manner. At the post level, “fashion baseball” is associated with insufficient baseball knowledge and recent fan influx. In first-level comments, the term functions as an evaluative label related to participation styles and fan authenticity. In second-level comments, meanings are negotiated through argumentative interactions, wherea in third-level comments, the discourse is fragmented into localized conflicts. Therefore, fan identity is continuously reconstructed through interaction and indexical meanings accumulate across discourse layers.
