The picture clearly shows Fat's robe open, and is clearly displaying the area of his anatomy where a penis would be - IF HE HAS ONE. Fat is the king of trying to win one over on people by technically not lying. If we're seeing the portion of his body where a penis would be and he's still adamantly declaring it's not his penis, could that be his admission that he is currently post-op, but hasn't socially transitioned yet? Could being a eunuch be one of those kinky things that he's in to? And if his penis isn't on his body, does he have it in a jar as a memento, or did the surgeon save it as a scientific oddity?
