He's boxing. He won the first player. The second player happens to be a girl. He expresses his displeasure about this subtly. He knocks her down but she gets up on 7. He knocks her down again, she gets up on 9. At this point he vocalizes his frustration. "Mom, this girl I'm playing is tough!" Finally he knocks her out. He does quite the "victory dance" over that one.
I'm thinking.... this is good training for your future. You gotta learn not to get the shit knocked out of you by some girl.
