You change your mind 
Like a girl changes clothes 
Yeah you, PMS 
Like a bitch 
I would know 
And you
Over-think 
Always speak 
Cryptically
I should know 
That you're no good for me 
Cause you're hot then you're cold 
You're yes then you're no 
You're in and you're out 
You're up and you're down
You're wrong when it's right 
It's black and it's white 
We fight, we break up 
We kiss, we make up
You!
You don't really want to stay, no 
You!
But you don't really want to go-oh
You're hot then you're cold 
You're yes then you're no 
You're in and you're out 
You're up and you're down 
We used to be 
Just like twins 
So in sync
The same energy 
Now's a dead battery
Used to laugh (used to laugh)
Bout nothing (bout nothing)
Now your plain (now your plain)
Boring (boring)
I should know (I should know)
you're not gonna change (change)
Cause you're hot then you're cold 
You're yes then you're no 
You're in and you're out 
You're up and you're down
You're wrong when it's right 
It's black and it's white 
We fight, we break up 
We kiss, we make up
You!
You don't really want to stay, no (woah)
You!
But you don't really want to go-oh (ohhh)
You're hot then you're cold 
You're yes then you're no (no!)
You're in and you're out 
You're up and you're down (you're down!)
Someone call the doctor 
Got a case of a love bi-polar 
Stuck on a roller coaster 
Can't get it off this ride
You change your mind 
Like a girl changes clothes 
Cause you're hot then you're cold 
You're yes then you're no 
You're in and you're out 
You're up and you're down
You're wrong when it's right (When it's right)
It's black and it's white 
We fight, we break up 
We kiss, we make up (We make up)
You're hot then you're cold (Ohhhhhhhhhhhh)
You're yes then you're no 
You're in and you're out (Oh!)
You're up and you're down (Ohhhhhhhhhhhhh)
You're wrong when it's right 
It's black and it's white (Oh!)
We fight, we break up 
We kiss, we make up
You!
You don't really want to stay, no (woah)
You!
But you don't really want to go-oh (ohhh)
You're hot then you're cold (Cold)
You're yes then you're no (No)
You're in and you're out 
You're up and you're down (Dooooown)
