The purpose of this study is to examine the negative effects of spectator dysfunctional behavior (SDB) on other spectators’ anger, rumination, and revisit intention. More specifically, in Study 1, we show that SDB (vs. spectator normal behavior [SNB]) elicited other spectators’ anger and reduced revisit intention. Anger significantly mediated the relationship between SDB (vs. SNB) and revisit intention. The negative effects of SDB and anger on revisit intention became positive as team identification increased. In Study 2, we demonstrate that rumination regarding SDB incidents evoked focal spectators’ anger and decreased revisit intention. Anger significantly mediated the relationship between rumination and revisit intention. Furthermore, the negative effects of rumination and anger on revisit intention were more significantly reduced in a high-level team identification group than in a low-level of team identification counterpart. Overall, the current work makes contributions to the sport management literature by shedding light on the dark side of sport spectatorship.
