Lyrics

Katy, Do you take Alexander
To be a your   @ wedded husband?

I do.

Alexander,
Do you take Katy to be your lawfully wedded   ?

You change your  
Like a girl changes  
Yeah, you PMS like a   I would know
And you over-think always   cryptically
I should   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 then you're out
You're   then you're down

You're wrong when it's  
It's black and it's  
We fight, we   up
We kiss, we   up

(You) You don't really wanna stay, no
(You) But you don't really wanna go

You're hot then you're cold
You're "Yes" then you're "No"
You're in then you're out
You're up then you're down

We used to be just like   so in  
The same   now's a dead  
Used to laugh 'bout   ,
now you're   boring
I should know that you're not gonna  

'Cause you're hot then you're cold
You're "Yes" then you're "No"
You're in then you're out
You're up then 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 wanna stay, no
(You) But you don't really wanna go

You're hot then you're cold
You're "Yes" then you're "No"
You're in then you're out
You're up then you're down

Someone   the doctor
Got a   of a love bipolar
Stuck on a roller  
Can't get   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 then you're out
You're up then 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're hot then you're cold
You're "Yes" then you're "No"
You're in then you're out
You're up then 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 wanna stay, no
(You) But you don't really wanna go

You're hot then you're cold
You're "Yes" then you're "No"
You're in then you're out
You're up then you're down, down
Legend

Meaning

The song is about a real guy - an ex-boyfriend who she could never get a read on. Said Perry, "One day this person would send me a text and I would be so thrilled about it because I had been waiting for some kind of sign - a smoke signal. He would be all interested and then I would just lose him, or one day he would want to see me and then one day he wouldn't. I didn't know what was wrong with him, if he was bipolar, or if he was wearing a mood ring. I took the theme and the song kind of spilled out of me.
