Cristiano Ronaldo first popularized the Siuuu during his time at Real Madrid, performing a spinning jump and landing with arms outstretched while shouting the word, drawn from the Spanish 'si' for yes. Clips of the celebration spread across YouTube, TikTok and football fan pages, and fans and opponents began copying it worldwide. This loud version emerged as editors amplified the audio for comic effect, fitting the wider scream meme trend online. It remains popular because the shout is instantly recognizable, even without any football footage.
