Your move, 'Bad Blood.'

The Taylor Swift Lyric Guessing Game for 1989 began in earnest Monday, when Swift talked to Rolling Stone about her new song "Bad Blood," which addresses an unidentified female celebrity who stabbed her in the back. The Internet zeroed in on Katy Perry as the target, and Perry subsequently tweeted a shade-filled response ("Watch out for Regina George in sheep's clothing").

We don't know the actual lyrics to "Bad Blood" yet, so it's currently anyone's guess if there will be call-outs to kitty cats, green hair and all-denim VMA ensembles. Assuming it contains classic Swift songwriting, the lyrics are going to get hyper-specific. Like, even people who don't know the actual situation (so, all of us) are going to be able to puzzle it out. Despite what Swift says -- she notes she doesn't want guessing games about "Bad Blood," merely people to relate their own experiences to it -- it doesn't seem like a super-likely response given the specific directions she often puts into her tunes. They're practically a public roadmap to who pissed her off when and why. 

Did Katy Perry Confirm Taylor Swift's 'Bad Blood' Song Is About Her?

What will the subject of "Bad Blood" be in store for on 1989? Below, some of Swift's best one-person-specific lyrics. We're not talking the generic fun of "We Are Never Ever Getting Back Together"; rather, her confessional words about a very specific someone that pepper some of her best songs. Remember, it's not just the exes: She saved her harshest lyric for an actress.

1. "She's not a saint/ And she's not what you think/ She's an actress, whoa/ She's better known/ For the things that she does/ On the mattress, whoa." -"Better Than Revenge"
Allegedly about: Camilla Belle (who dated Jonas after Swift)
