The memes are confusing, hilarious, and in typical social network fashion, have spread like wildfire in a matter of hours. However, now that the Marvel movie is out, fans have been tweeting Avengers: Infinity War spoilers with no context - posting photos, videos, and GIFs, that tell different parts of the story in a way only people who have seen the movie would understand.
