It can also just mean that winter is literally coming, though on Game of Thrones, 'winter' has a meaning that's a whole lot darker than just less sunlight and more snow. It's also a thing multiple characters say throughout the series, and it has become the easiest way to say that Game of Thrones or something related to it is on its way.
It's the title of the first episode ever, but it's also the Stark family motto. On Wednesday, April 14-exactly two years after the final season premiered and three days before the 10th anniversary of the series premiere-the Game of Thrones Twitter account sent fans into a tailspin when it tweeted, 'Winter is coming.' Now, that phrase can mean a lot of things to a GoT fan. Game of Thrones may be over, but the world of Westeros will never truly leave us.
