25THE NINE NINE CHANT
The 99 are loyal to each other and their station. They're all great cops alone but make an even greater team. Of course, all great teams of a chant. In the show, the team chants "Nine-Nine" to pump up. Sgt. Terry Jeffords is usually the one that shouts it
out. It gets them all pumped up no matter the situation. It doesn't matter if it's a party or a crime.
However, the chant wasn't something the writers came up with. In fact, Terry Crews (Jeffords) would yell "Nine-Nine" to pump up the cast. According to Mellisa Fumero, Crews would yell the chant Monday mornings before shooting. Soon it caught on and the writers put the chant in the show.
