That was all steroids, I bet the losing kid lifts all the time. He's just not on steroids Luke the other kid. You look like a great wrestler when you are stronger. Everything works.
Based on the gesture that the official makes at 4:05 pointing towards his forehead, and the action that occurs at 3:56 and immediately again at 3:58, I am guessing that the official is warning red not to headbutt green.
