This is the funniest gif that I've seen in a while - It's rare for one to force an audible laugh out of me. A kid in a suit is dancing with a small child when another child comes over and pushes her way in, looking to dance. Unfortunately for her, the boy in the suit isn't having any of it and stares her down. The result is her walking away crying as he continues to dance... by himself. Some have said it was because the little kid in the blue dress was black, but I don't believe that. I think he was just trying to let her know that he wasn't happy with how she pushed the other kid out of the way.
There is huge reaction gif potential in this one.
