Yes everything is a JoJo's reference if you try hard enough. for example having a habit is a JoJo's reference becuase kira bit his nails. having a sign of fear is a JoJo's reference (and mine is the same a josukes!) and even peeing is a JoJo's reference. Eating fried chicken is a JoJo's reference, drinking liquid is a JoJo's reference, breathing is a joJo's reference, and literally just existing is a JoJo's reference.
