What do the French say when they are chanting at a sporting event? In English, people might say, "Go! Go! Go!", or chant the MVP's name/number while clapping rhythmically. What's a substitute for, "Go! Go! Go!"?
In France, chanting is usual at soccer games. There's a lot of different songs depending on the club and players.
Here are some classics:
"Qui ne saute pas n'est pas français" (for the French national team, but the end can be changed to whatever team you're supporting, eg "qui ne saute pas n'est pas marseillais") - meant to encourage people to jump in place to produce a giant rumble
"Allez les Bleus" (again this would be for the national team based on the jersey color, but can be used for other teams by matching their jersey colors)
Victory chants: "On a gagné" (for any victory), "On est en finale" (for a qualification for the finals of a tournament) and "On est les champions" for a championship win; "Et 1, et 2, et 3-0" for a large goal difference.
But really there are many club specific chants too, and sometimes the name of a particularly outstanding player will be chanted.
