Personally, I think that what made this Youtube Rewind particularly shit (which is pretty impressive, considering how shit the others are) is the fact that... I honestly didn't recognize anything in it. I had no idea who any of the youtubers were. I don't play Fortnite, so I didn't really get any of those references, I've never heard of Bongo Cat, and then there was this whole part just dedicated to... Eating Korean food? Is that a thing? Why is that a thing?
I think the only thing I actually recognized in Youtube Rewind was Lucas the Spider.
