Fimbulwinter FTW
Hmmm, for "art/entertainment/poetry/story" purposes, I interpret the phrase "Winter is coming" as referencing the "end of the world/Ragnarök" Fimbulwinter from Norse mythology. There is a REASON its a common phrase for literature/arts and such, even if the majority of the population doesn't understand the significance. Not sure how HBO can issue a takedown on that with a straight face, but I assume their lawyers aren't well versed outside of law classes?
