Lil Scrappy went ballistic Wednesday after his daughter was repeatedly passed over during a contest at the Nickelodeon Suites Resort in Orlando ... because he believes the staff favors white kids.The "Love and Hip Hop" star was at the pool with Momma D and their 9-year-old daughter Emani. They were there for a game where the staff calls kids up on stage for contests. Momma D tells TMZ ... Scrappy became furious when the staff kept skipping over his daughter and other black kids. In the video you see Scrappy confront the host. It's hard to hear him, but Momma D tells us he said, "You need to pick my daughter. This is some racist-ass s**t."The person shooting the video tells us they support Scrappy's position in the situation.The woman implores Scrappy to get off the stage, and then Momma D steps in and repeats the claim.Emani finally pushes her dad off stage.A rep for the resort tells TMZ ... they don't discriminate on race, color, religion, sex, or national origin. They add that participants must follow specific protocol ... and that Scrappy's daughter did participate in the show.
