Gangnam Style is a 2012 single by South Korean artist PSY, released with a music video that became one of the biggest viral hits on YouTube. Its horse-riding dance, catchy chorus and comedic style helped it spread across memes, parodies and reaction edits worldwide. The song remains a familiar shorthand for early 2010s internet culture, so short clips are still used when creators want a recognisable viral song that instantly brings back that era.
