Working with the Make A Wish Foundation, the Carolina Panthers made Beam coach for the day during the team's public practice Friday, complete with a coach's press conference, his own assistant, a trading card and a dance-off with quarterback Cam Newton.
"The coolest part was watching the players dancing with him," mom Meredith Beam, a 30-year-old nurse from Denver, North Carolina, tells PEOPLE.
Their "stanky leg" dance, which has since gone viral on social media thanks to fans like Donnie Wahlberg, was the icing on the cake after a pretty sweet couple of hours at Bank of America stadium in Charlotte.
Dad Jesse Beam, a 32-year-old physical education teacher, tells PEOPLE exclusively, "It was the proudest I will ever be. It might be one of the best days of my life. To see Braylon, who has battled cancer, get the opportunity to live out a dream, it was surreal for me to see him so happy after all he's faced these last several months."
Beam has a brain tumor behind his optic nerve that is slowly taking away his vision. A recent scan showed the tumor might be shrinking, but his parents are helping make sure he makes the most of every day.
Jesse and Braylon became a viral sensation a few months ago when the father and son duo decided the best way to get through Braylon's weekly chemo treatments was to dance. Together they work up a routine and perform at regular "Friday dance parties" at St. Jude Affiliate Novant Health Hemby Children's Hospital where Braylon is being treated.
"It's fun!" Braylon says, admitting he still prefers his signature twerk to the "stanky leg" moves he's currently known for.
Even Ellen DeGeneres took note, having the family on her show and helping launch the "Just Keep Dancing" hashtag that has people all over social media honoring the 6-year-old with their own moves.
At the Panthers scrimmage game, Braylon was all smiles, but mom Meredith admits she lost track of how many times she cried at the stadium. "It was a very proud moment. We are extremely thankful and very blessed to have such a wonderful son that can touch so many lives. No matter what's happening, he's smiling, and people have really embraced that."
