The sound comes from South Korean baseball cheerleading, where the Ppikki Ppikki routine was performed during games as a light dance break. A clip of cheerleader Lee Ju-eun performing the seated moves while keeping a calm expression spread widely on TikTok in 2024, turning the routine into an international challenge. Users copied the exact gestures, filmed covers in uniforms, classrooms and bedrooms, and remixed the loop for transitions. Its simple choreography and short length made it easy to learn, which helped it stay popular beyond the original sports setting.
