Okay I'm just brainstorming here: In the starting of the video, I see a cross and after that the "skin to bone 8.4" comes. Maybe I'm wrong but maybe they are trying to emphasise on Christianity. Maybe the 8.4 is actually 8:4, and maybe they mean 8:4 of one of the books of the bible or something. I don't know coz I'm not Christian. Im most probably wrong but I'm just giving an idea.
