The brunette isn't even trying. First she saw the size of that fat-ass and thought, "Okay, we can do this." Then she got a little closer and saw the grease stains on the shirt and thought, "Alright, it's bad but not a deal-breaker. We can still pull this off." And then she saw the hole in his filthy grease stained shirt and just lost her fucking mind. p.s. you will also notice that the blonde is pretending to have her hand on fatty's back.
