Warren Sapp isn't just a QB Killa ... he's a DANCE FLOOR KILLA ... and he proved it this weekend when he went all H.A.M at his NFL Hall of Fame induction party.
Sapp -- sporting his newly acquired HOF jacket -- was the guest of honor at the special Warren Sapp party tent in Canton, Ohio ... where stars like Dan Marino, Lawrence Taylor, Marshall Faulk and Deion Sanders came by to party with the big man.
But during the party, Sapp -- clearly feeling the adrenaline -- grabbed the mic and told the crowd, "One time like my dog Ray Lewis used to do."
Then he straight BROKE. IT. DOWN.
Ya gotta watch the clip. Dude's got moves.
