Desiigner flow. After scoring his first No. 1 on the Billboard Hot 100, the G.O.O.D. MC showed off his skills during a rapid-fire freestyle with Tim Westwood TV.

With quick hand movements, gun gestures, impromptu dance moves, and his now famous facial expressions, the 18-year-old delivered a capella rhymes about being like Hannibal Lecter with his mask on while “moonwalking seeing moon people.”

Upon topping the charts this week, Desiigner received props from his G.O.O.D. Music brothers Pusha T and Kanye West, who said he was “so proud.”
