Over just four years, Morocco has emerged as one of the most accomplished teams in international soccer. In 2022, the country made history as Africa’s first semifinalist in the World Cup. Morocco then shattered the world record for the longest winning streak in international football in 2025, captured the 2025 FIFA Arab Cup, and earned the title of 2025 Africa Cup of Nations champions. Now, Morocco is making even more noise at the 2026 World Cup, aiming to surpass its Qatar performance. Along the way, the country’s fans have gained a reputation for their rowdiness, including frequent whistling during games. Here’s why Morocco fans are often heard whistling during World Cup matches.
The main reason for the recurring whistles is that fans are trying to create a hostile atmosphere for the opposition, generating loud noises in hopes of distracting opposing players. While some fans whistle as a form of cheer, Moroccan supporters typically use whistling to voice their disapproval—whether they are unhappy with the opponent, the coach, or the referees. The piercing hiss can be a potent form of booing, signaling their displeasure.
Whistling also functions as a tactical move to disrupt opponents’ communication on the pitch, acting as a “12th man” that can occasionally give Morocco a leg up. Beyond the whistles, Moroccan fans are known for their distinctive “Viking clap.” This chant begins in silence, but once the signal is given, the entire stadium fans out their arms in front of them while shouting “SIR,” a word meaning “go” in Darija, the Moroccan dialect of Arabic. The Viking clap can grow louder and faster, creating a formidable distraction for opponents.
In 2026, Morocco is making its seventh all-time World Cup appearance, continuing a string of strong performances across consecutive tournaments. The team first qualified for the World Cup in 1970, and after advancing beyond the group stage for the first time in 1986, it wasn’t until 2022 that Morocco began to truly shake the knockout rounds. After their semifinal run in 2022, where they fell to France, Morocco again found themselves matched up against France in the 2026 quarterfinals.
