Chelsea Dagger was released in 2006 by Scottish rock band The Fratellis as a single from their debut album Costello Music. Its chorus chant became widely adopted in sport, most famously as the goal celebration song for the Chicago Blackhawks in ice hockey and by football fans in the UK. The short looping hook later spread online through sports edits, highlight reels and meme videos, where its wordless singalong made it easy to reuse. It remains popular because it signals celebration instantly without needing lyrics or context for new listeners today.
