YouTube is weird as f*** the stuff you think won't go viral ends up being the very thing that does go to viral. My channel has over 1700 Total videos I've only had one to get over 100,000 views ironically enough I almost didn't post that particular video because I didn't think it would do well just the other day I got an email from youtube saying congratulations your video reached 100,000 views.
It's a YouTube short by the way and to be honest the video looks like crap you can barely figure out what's going on in the video and I do believe that's what caused it to blow up because people were re-watching over and over trying to figure out what everyone liked about the video when in reality there was nothing special about it it just wasn't clear enough for people to figure it out.
