If you've stalked the athletes on social media, you've probably seen that they are constantly using the hashtag FIOFMU. "I’m so happy the world gets to see what amazing experiences Navarro athletes go through on a daily basis. I am so honored to have been apart of that experience and beyond grateful for the long lasting friendships I made from my time being in Corsicana. #FIOFMU," tweeted one of the stars of the series.

Naturally, a fan of the cheerleading series took to Twitter to ask about what the letters stand for, writing: "Now that I’ve spent 6 hours of my life watching the entire cheer documentary on Netflix , I feel like I have the right to know what  #FIOFMU  means." 

Unfortunately, it appears the coded message is for Navarro cheerleaders only! 

Someone posted a question on Ask.Fm:  "If you make the Navarro cheer team, when do you find out what FIOFMU means?" Sarah Sweet responded, "Not until the very very end of your year."

While it looks like these close knit athletes are not about to share their secret code anytime soon, Urban Dictionary states that FIOFMU means, "Fight it out, f--k 'em up." Though, we cannot verify if that is entirely accurate.

Netflix's docuseries Cheer is available to stream now.
