It got all "Stomp the Yard" in the Staples Center last night ... when Clippers owner Steve Ballmer busted out some EPIC dance moves during the game ... and Magic Johnson LOVED IT!!!
It all went down when Fergie came out to perform during the Clips vs. Lakers game ... when the music took hold of Ballmer's body ... and the body parts began to fly!!!
"That's an owner who can dance and own the team all at the same time," Magic told us on his way out of the arena. "He got better moves than me!"
