It’s Lil Chuckee. He’s a young (I think 13) rapper/dancer from New Orleans/Atlanta. He has a grill and likes to hold money in pictures. He also mentions God a lot and started a charity for kids in New Orleans. He got his name from the movie Child’s Play, because he says he has a mature mind trapped in a child’s body. Now you know.
Ever wonder who that little kid is that's always chilling with Lil Wayne?
