In this chapter, we're introduced to a new character, a young man who's about to be "hit on" by a "knoby guy" . He's a little nervous because he's just been "stunned" by the "cock-jerking" that's been going on in his head. He wants to know what's going on, but he can't seem to figure out how to get the "stimulus" out of his system. So, he decides to "shake 1 huff" , which basically means he'll "touch my cock" if he doesn't get what he wants out of this encounter.
