"This Why We Can't Have Nice Things"
The telling lyrics: "It was so nice to be friends again / There I was, giving you a second chance / But then you stabbed my back while shaking my hand / And therein lies the issue / Friends don't try to trick you / Get you on the phone and mind-twist you / And so I took an ax to a mended fence"
Who it's supposed to be about: Kanye West
Why? Swift references the infamous phone call between her and West and how he and Kim Kardashian later twisted the truth about what they talked about.
