Gangnam Style was released in 2012 by South Korean singer PSY and became a global viral hit after its music video spread on YouTube. The exaggerated horse riding dance, colourful outfits and repetitive hook made it easy to copy and parody, helping the song reach audiences far beyond K-pop fans. It was the first YouTube video to pass one billion views, and short clips of its chorus still circulate in edits and memes as a shorthand for flashy confidence and dated but recognisable internet humour.
