As it turns out, Taylor has extremely specific deal breakers. Don't you dare whistle through your nose.
"We Are Never Ever Getting Back Together"
Most people think this song is about Jake Gyllenhaal. And it is. It was inspired by a time when Gyllenhaal ate a Kit-Kat bar without breaking the pieces apart, just bit right into the whole thing like an animal.
"Red"
This song sounds like it might be another tale of torrid love with Gyllenhaal, but it's actually about a time Conor Kennedy spilled an entire soda at a restaurant.
"Dear John"
This song is obviously about John Mayer. Specifically, it's about how Mayer pushed Swift to the edge by pronouncing "library" like "libary."
"Mean"
This song is often thought to be about a cranky music critic, but the initial inspiration was actually a Starbucks barista who gave Swift a weird look when all she did was ask for almond milk.
