Finish the lyrics. You were with your friends partying
When the alcohol kicked in
Said you wanted me dead
So, you show up at my home, all alone
With a shovel and a rose
Do you think I'm a joke?
'Cause people like you always want back what they can't have
But I'm past that and you know that
So you should turn back to your outback tellin' them trash

Out at the shack. Kick' em out of the house, make them pay, 'cause it our day. You actin all Cleshae, and you're finally dead. Hooray!

Tell all of your friends that I'm crazy and drive you mad

That I'm such a stalker, a watcher, a psychopath

Then tell them you hate me and dated me just for laughs

So, why do you call me and tell me you want me back?

You maniac

You maniac

(Maniac, some may say that I'm) You maniac

(Maniac, some may say that I'm) You maniac

(Maniac, some may say that I'm)

You just went too far

At your car, called me crying in the dark

Now you're breaking my heart

So, I show up at your place right away

Wipe the tears off of your face

While you beg me to stay

Well, people like you always want back what they can't have

But I'm past that and you know that

So you should turn back to your outback tellin' them trash

Tell all of your friends that I'm crazy and drive you mad

That I'm such a stalker, a watcher, a psychopath

Then tell them you hate me and dated me just for laughs

So, why do you call me and tell me you want me back?

You maniac

You maniac

(Maniac, some may say that I'm) You maniac

(Maniac, some may say that I'm) You maniac

(Maniac, some may say that I'm)

Psychopathic, don't be so dramatic

We had magic, but you made it tragic

Now you're manic, honestly I've had it

Listen to yourself, think you need to get some help

Tell all of your friends that I'm crazy and drive you mad

That I'm such a stalker, a watcher, a psychopath

Then tell them you hate me and dated me just for laughs

So, why do you call me and tell me you want me back?

You maniac

You maniac

(Maniac, some may say that I'm) You maniac

(Maniac, some may say that I'm) You maniac

(Maniac, some may say that I'm)
