The original shout comes from Cristiano Ronaldo's trademark goal celebration, in which he leaps into the air, lands with his arms out and shouts Siuuu to the crowd. Fans and editors copied the chant across football highlights, TikTok edits and meme videos, and distorted versions soon followed as a way to make the celebration louder and funnier. The warped sound stuck because it keeps the instantly recognisable chant while adding the exaggerated, bass-heavy style favoured in short-form edits, so it still appears whenever a clip needs an over-the-top winning moment.
