« 'Boom' is my heart. The 'kack' is my soul. Apparently when I choreographed I didn't realize that I said 'boom-kack' 'boom-kack.' I had no idea I was doing it and then I realized that it's every time I felt like the fight in my soul - the boom and the kack - was like my heart. It was like the love of it - my heart and soul. »
