FOMO? It's definitely a thing, a big one is piracy - a feeling that you HAVE to watch e.g. Game of Thrones as soon as possible because else you're missing out on the hype, the ability to talk with people about it, and if you're not fast (or disconnected from social media) you'll get major spoilers hitting you unexpectedly.

I mean I haven't watched Endgame yet because my family is still catching up but I've had all of the major plot points already spoiled thanks to my Reddit addiction. That kinda sucks.
