Arrrrr, this slave be a pirate! Well not really, but Kendall and Sara are making him speak like one as Sara kicks him in the balls. It's just a game they like to play where they make him humiliate himself while they systematically him without pity. And it works because he sounds completely ridiculous talking like a pirate as the kicks to his nuts keep coming. Which ultimately is great because the girls find it hysterical, as the mix of his humiliation and pain is pure amusement for them.
