In this short scene, we learn that the young master is in the middle of a "massage" . He's so excited that he's about to "shake really a massage" , which is a fancy way of saying, "shake my hand and I'm going to give you a good massage." We're not sure what this means, but we're guessing it's a fancy massage . The young master's got a lot on his mind right now, so we'll just let him do what he wants.
