A trademark goal celebration by football player Cristiano Ronaldo.

It was first seen when celebrating scoring a goal for Real Madrid and has since become a trademark move even after moving to another club.
After scoring the goal Ronaldo ran, performed a mid-air pirouette, planted his feet and yelled a guttural "Siu!".

The spelling of the phrase is not widely agreed upon, but it equates to "Si" which means "Yes" in Portuguese.
The scream? The players know I always do that shout when I score a goal or when we win"

"It’s our shout, from Real Madrid."

-Ronaldo regarding "Siu" on Spanish TV station Cuatro after the 2014 Ballon d'Or ceremony.
