Every KBO team employs a full-time professional cheerleading squad that performs choreographed routines in front of the dugout throughout every inning — not just between. Each team has signature chants for every player in the batting order. Fans don't just cheer; they perform. Watching KBO on SOOP with the sound off is like watching half a movie. Turn the audio on. The experience is part K-pop concert, part ballpark, and it's the single biggest reason 12.3 million Koreans showed up in 2025 — a league record. The energy transfers through the screen. Lotte Giants fans in Busan are particularly intense — bring orange plastic bags, a thundersticks, and expectations.
