When BLACKPINK released their music video for “BOOMBAYAH” in August 2016, it became an instant hit.

And now, over four years since then, it is now one of the only K-Pop group music videos to reach one billion views.

Please check out some lesser-known facts about “BOOMBAYAH” below!

1. Their bikes were not moving.
   Each member’s bike was stationary. In reality, what made the girls look like they were actually riding them was the moving background.
2. Jisoo’s head was the only one poking out.
   When BLACKPINK danced in a straight line, Jisoo did her best to follow the choreography of two people sticking their heads out—but she ended up being the only one seen behind Lisa!
3. The background was made of bottles.
   Mineral water bottles were used to make the gorgeous background the girls used for their solo scenes.
4. The concept behind “BOOMBAYAH” was “troublemakers”.
   The girls wore chains, chokers, and fishnets with their school girl-like costumes to embody the “troublemaker at school” concept of the music video.
5. Rosé had a difficult time doing her iconic move.
   The move where Rosé slides across the floor may look easy enough, but it was one of the most tedious moves for her. Her clothes kept getting stuck and she even sustained some minor injuries.
