Lap Dance Nika was a name given to the alter ego to Minaj by Team Minaj over Twitter, which Minaj herself confirmed as the official name. “The one that comes out with the lap dances on stage, I think that’s Lap Dance Nika. Let’s call her Lap Dance Nika,” she said on Los Angeles’ Power 106. “Some of my fans, my Team Minaj Barbz, they've called me that sometimes on Twitter, so I thought it was cute, so we'll call her Lap Dance Nika.”
She later said that she isn't going to do lap dances on Britney Spears' Femme Fatale Tour. “This will be my last round of lap dances,” she said on the interview. “When I go [out] with Britney, no more lap dances.”
Nika is rumored to appear whenever a lap dance is needed (like the Super Bass music video, the performance at the Billboard Awards 2013, and the Dance (A$$) (Remix) video).
