This is a chant done by Christiano Ronaldo after he scores a goal. He dashes towards the crowd, jump while doing a pirouette in the air and land with arms and legs spread open chanting SIUUU along with the crowd.
He shares the G.O.A.T. title of world football with Lionel Messi.
A chant made by Cagliariman and his clowns after he gets a chance to perform a tap-in against plumbers and part-time fire fighters; or when he luckily gets a penalty after ghosting against top teams.
Wait till he scores a tap-in now and watch him Siuuu all around the pitch. Fraud.
