(I'm a lunatic, I'm a b**ch, I'mma, I'mma, I'mma)

(I'm a lunatic, I'm a b**ch, I'mma, I'mma)

Let me paint the picture for ya

Heard my ex talking trash 'bout my, on the internet

Seeing red, next thing I know

I'm outside his work with the baseball bat 'cause I understood her

Hello 911, think that I'm on one

Get the ambulance, I might mess him up

'Cause I heard what you said the other night, night

So if you got the nerve then say it twice, twice

(Say it)

I'm a lunatic, I'm a b**ch

I'mma, I'mma, I'mma light up all your sh*t

Blow a kiss like (Woo-ooh-ooh-ooh)

Push you in the, tiny d*ck

Look at, look at, look at, look at what you ​did

I'm a lunatic (Woo-ooh-ooh-ooh)

I'm a lunatic (Woo-ooh-ooh-ooh)

I'mma, I'mma, I'mma

I'm a lunatic (Woo-ooh-ooh-ooh)

I'mma, I'mma, I'mma

If we're being straight up I faked it the whole time

You couldn't get it to stay up so I got off online

Yeah, I tried to play it nice and that lasted 'bout a week

Now I kinda wanna fight, are you happy to see me?

Hello 911, think that I'm on one

Get the ambulance, I might mess him up

'Cause I heard what you said the other night, night

So if you got the nerve then say it twice, twice

(Say it, you can't say it, yeah)

I'm a lunatic, I'm a b**ch

I'mma, I'mma, I'mma light up all your sh*t

Blow a kiss like (Woo-ooh-ooh-ooh)

Push you in the, tiny d*ck

Look at, look at, look at, look at what you ​did

I'm a lunatic (Woo-ooh-ooh-ooh)

I'm a lunatic (Woo-ooh-ooh-ooh)

I'm a lunatic (Woo-ooh-ooh-ooh)

I'mma, I'mma, I'mma

I'm a lunatic (Woo-ooh-ooh-ooh)

I'mma, I'mma, I'mma

I'm a lunatic (Woo-ooh-ooh-ooh)

I'mma, I'mma, I'mma

(I'm a lunatic, I'm a b**ch, I'mma, I'mma, I'mma)
