    Southern AE greatly modified by a 1st-generation Scottish-American mother, and growing up abroad.
    The primary meaning of "kick ass" is to win a fight. By analogy, it means to win a game or competition-- at its loosest, it means to do exceptionally well. So the movie was exceptionally good, it really "knocked you out," it kicked ass.
