You don't even have to be a Taylor Swift fan to know about her famous "scarf" lyric.
The 32-year-old US pop star re-released one of her most beloved hits, All Too Well, in November last year, gifting fans with a 10-minute version of the heartbreak anthem long rumoured to be about her short-lived romance with US actor Jake Gyllenhaal in 2010.
One particular line in the song has since become a viral anecdote, in which Swift sings: I left my scarf there at your sister's house / And you've still got it in your drawer even now.
Gyllenhaal's sister, US actress Maggie Gyllenhaal, has even been asked about the accessory in various interviews, pleading ignorance to the scarf's whereabouts.
Now, speaking about the short film she directed for the track at the Toronto International Film Festival, Swift has revealed the scarf was not so much a physical reference, but a "metaphor".
