Cristiano Ronaldo's celebration became famous during his years at Real Madrid, where he would run, jump, spin in the air and shout Siuuu on landing, a take on the Spanish word for yes. The pose and shout were repeated at Juventus, Manchester United and Al Nassr, with crowds joining in around the world. Clips of the moment spread widely on social media, were remixed into edits and soundboards, and the elongated zooo version became a shorthand meme for scoring, winning or showing off.
