siuuu

[pronounced siuuu/ suuu]. An exclamation of joy caused by a win or particularly good news. The exclamation comes from Cristiano Ronaldo, who gave a shout after Real Madrid’s winning match against Chelsea London: ‘siiii’ ‘yes’. The exclamation soon became the basis for the characteristic ‘cieszynka’ (in football, it’s a display of joy), which for younger teenagers is not only the source of numerous imitations, but also a synonym for ‘essa’.

The word has been noted in English slang since 2021 (Urban Dictionary).

Example of usage:

1. siuuu. The champion’s goal! /h/
