Fan chants are a long-standing part of K-pop concert culture, where audiences chant members names and key lines in rhythm with a song. For BTS, the best known chant calls out the seven members in order before shouting the group name, and ARMY, the groups official fandom, performs it at concerts and fan events. Clips of the chant spread through concert recordings, fan cams and social media edits, and it remains popular online as a quick way to show support and mark a BTS moment.
