Big surprise, I didn't see it coming
All your lies caught me with my pants down
Pick it up, I hope you're good at running
'Cos you don't wanna see how ugly I can be
Lie awake, planning my revenge out
Big mistake to mess around with me
Don't you know I got a reputation to uphold
So, baby, call me
Psycho, it's a compliment
Crazy, I invented it
Oh, write me down in history
As the ex-girlfriend
Chalk it up to lessons learned
Play with fire, you'll get burned
I gave you all the best that I could be
It's only fair you get the worst of me, the worst of me
Remember when you used to call me 'honey'
And now it seems I'm sticky more than sweet
Just admit, I'm not what you expected
Tougher than you ever thought I could be, baby
Psycho, it's a compliment
Crazy, I invented it
Oh, write me down in history
As the ex-girlfriend
Chalk it up to lessons learned
Play with fire, you'll get burned
I gave you all the best that I could be
It's only fair you get the worst of me
And I'm not so bad
But you make me sad
And I just had to get you back
So, call me
Psycho, it's a compliment
Crazy, I invented it
Oh, write me down in history
As your very psycho ex-girlfriend
Psycho, it's a compliment
Crazy, I invented it
Oh, write me down in history
As the ex-girlfriend
Chalk it up to lessons learned
Play with fire, you'll get burned
I gave you all the best that I could be
I gave you all the best that I could be
It's only fair you get the worst of me
