삐끼삐끼 춤

The 'Bbi-kki Bbi-kki Dance' began to gain significant popularity in June 2024. Initially, it was known as a strikeout song among KBO League KIA Tigers baseball fans. However, in June 2024, a video of cheerleader Lee Ju-eun performing the Bbi-kki Bbi-kki Dance while fixing her makeup went viral on YouTube and social media, spreading widely to the general public. From July 2024, YouTube algorithms caused a surge in views, leading to participation in challenges by domestic influencers and celebrities. Around the same time, its popularity extended beyond Asia, reaching global recognition in August 2024 when the New York Times published an article covering the dance and KBO cheering culture. Driven by this popularity, the 2025 KBO League even saw the advent of the "Great Out Song Era."

The 'Bbi-kki Bbi-kki Dance' (Korean: 삐끼삐끼 춤, pronounced roughly as 'Bpee-kee Bpee-kee Choom') refers to the dance performed to the KIA Tigers cheering squad's strikeout song. The name 'Bbi-kki Bbi-kki' was given because the music's pitch sounds like 'Bpee-kee Bpee-kee' to Korean ears. A unique aspect of KBO League cheering culture, an 'out song' is a simple musical and dance cheer performed by cheerleaders when the defensive team gets an opposing batter out. The core of this dance is to provocatively taunt the opposing team after a strikeout, with cheerleaders performing it with a poker face, relaxed, and nonchalantly, which is the key point. Because of this, opposing fans sometimes refer to it as the "annoying out song." The original music is a remix of jtL's 'My Lecon' by Indonesian DJ Prengky Gantay. The choreography is relatively simple, consisting of: waving hands with thumbs up in a semicircle from the shoulder to the side, repeatedly crossing and uncrossing both hands in an X-shape in front of the chest, bending the knees, and wiggling the hips.

The 'Bbi-kki Bbi-kki Dance' has garnered a very broad audience, starting from KBO League baseball fans and expanding to the general public, influencers, celebrities, and even international fans. It has spread across all ages and genders, particularly through short-form platforms like YouTube, Instagram, and TikTok. Its cross-border popularity was further demonstrated by the participation of Taiwanese professional baseball fans, US sports fans, and even global pop star Olivia Rodrigo in challenges. As of 2024, it enjoys the most cult-like popularity among dance-related memes in Korea.

The 'Bbi-kki Bbi-kki Dance' primarily carries the meaning of provocatively taunting the opposing team after a strikeout. Therefore, it's important to understand this context when using it. Additionally, copyright issues have been raised as a remixed version of the original song 'My Lecon' is used. The remix appears to have been created without the original author's permission, and the original song's copyright registration occurred after the challenge became popular. Since platforms like YouTube may take copyright-related actions, it's advisable to check copyright matters for commercial use. Some games have even replaced the music due to copyright issues upon release. As of 2025, some baseball fans are showing "resistance" to its excessive use, so it's best to use it appropriately according to the situation and atmosphere.
