I think the word "dafuq" is short hand for "what the fuck". It's kind of like LOL, IKR, or LMFAO in that sense. Most of the time, it represents confusion. That's how I understand the word anyway. Though if the author is going to improve their story, It would be best to provide more of an explaination as to how they can improve besides "Dafuq".
