No, the Falcons didn't just win the Super Bowl ... they just celebrated like they did -- 'cause linebacker Duke Riley led an insane locker room dance party after their W over the Eagles!!
ATL scored a big win over one of the best teams in the league Sunday night -- beating Philadelphia 24-20 -- and their post-game party was pretty epic.
Riley led the way with some awesome moves -- there was arm flailing, bouncing, leg gyrating ... it was awesome!!!
Backup running back Kenjon Barner also got into the circle to flash some of his dance moves -- and good times were had by all.
