Leap, spin, land, and shout: “SIUUU!” Cristiano Ronaldo’s celebration has become so iconic that entire stadiums now do it for him — even when he’s playing against them. As Ronaldo and Portugal chase the 2026 World Cup, here’s where that famous shout came from.
| Chant | “Siuuu” (Sí…!) |
| Originator | Cristiano Ronaldo |
| Reportedly began | 2018 preseason (USA) |
| Meaning | From Spanish “sí” (yes!) |
| Now | A global crowd chant |
Where “Siuuu” Came From
Ronaldo has said the celebration emerged around 2018, reportedly during a preseason friendly in the United States, and he simply kept doing it. The drawn-out “Siuuu” comes from the Spanish “sí” — an emphatic “yes!”
How Fans Took It Over
What makes it special is that crowds now produce the “Siuuu” en masse — a rolling roar that builds and bursts, sometimes even from opposition fans who can’t help themselves. It’s a chant about one player that somehow belongs to everyone.
A World Cup Staple
Wherever Portugal play in 2026, expect the “Siuuu” to echo around the stadium. More on Ronaldo’s celebration on Wikipedia.

A Celebration That Belongs to the Crowd
What started as one player’s celebration has become a piece of global football culture. The “Siuuu” now echoes in stadiums where Ronaldo isn’t even playing, gets recreated by kids on playgrounds, and even features as a celebration in football video games.
That is the rare power of the chant: it is instantly recognizable and impossible to resist joining. Wherever Portugal go at the 2026 World Cup, the leap-spin-“Siuuu” will follow, whether the crowd is cheering for Ronaldo or against him.
The shout itself is simple — a drawn-out take on the Spanish “sí” — but its reach is enormous. It’s now a selectable celebration in football video games, a playground staple, and a sound commentators reference the instant Ronaldo scores.
More than almost any modern celebration, it has detached from its creator: crowds do the “Siuuu” for the drama of it, whether they’re cheering Ronaldo or hoping he misses.
The celebration has even seeped into everyday football culture — kids recreate it on playgrounds, gamers trigger it in FIFA, and commentators brace for it the second Ronaldo lines up a shot. With this likely being his final World Cup, the “Siuuu” could deliver some of 2026’s most spontaneous, goosebump-inducing crowd moments. It pairs perfectly with the passion of the Portuguese national anthem.
