Songfacts®:

• "Chk Chk Boom" is a sonic assault of confidence. The song is a brash declaration of dominance, where Stray Kids promise to take on the world, blow past any competition, and win.
• The song has a Latin feel. While Stray Kids deliver most of the lyrics in Korean and English, they are spiked with some Spanish words.
• The track is the brainchild of the group's in-house production trio, 3Racha (Stray Kids members Bang Chan, Changbin, and HAN). They cooked up this Latin-styled hip-hop track with the help of their fellow Koreans, RESTART and Chae Ganghae and Dallas K.
  
  DallasK is an American producer and singer based in Los Angeles. He co-wrote and produced several of Fifth Harmony's singles, including "Work From Home," and "Down."
• Actors Ryan Reynolds and Hugh Jackman appear in the action-packed music video as Deadpool and Wolverine. They show up because Stray Kids recorded a song called "Slash" for the Deadpool & Wolverine movie soundtrack.
• Stray Kids debuted "Chk Chk Boom" live at Music Bank on July 19, 2024. It was released the same day as the lead single from their ninth Korean-language extended play, Ate.
• Ate debuted at #1 on the Billboard 200 chart, giving Stray Kids their first chart-topping album in America.
