BTS WORLD TOUR ‘ARIRANG’ IN BUENOS AIRES & SÃO PAULO: LIVE VIEWING - Special Trailer

Why Koreans care

“Arirang” is the name shared by a family of traditional Korean folk songs, making the tour title itself a prominent Korean cultural reference rather than an invented English slogan.

In the Korean comments

One commenter singles out a musical cue, writing in translation: “‘Fire’—I’ll never forget this legendary beat. Even after years, only BTS makes our hearts race.” The comment identifies “Fire” as the moment to listen for in the trailer.

What the words mean

보라해 (borahae, “I purple you”) sounds literally like turning “purple” into a verb. In these comments, it works as an affectionate BTS-fandom sign-off expressing love and continued support.
