Sweet but Psycho

艾娃·麥絲表示，歌曲中的“psycho”（瘋狂的）對於她來說意味著力量和勇氣，代表著一類有立場、堅毅且強大的女性，並不是瘋女人。它鼓勵著女生擁抱心中的自我，給予女孩表達自我的自信與力量，不用擔心讓別人說成是瘋子。艾娃·麥絲之前談過一次戀愛，她的前男友認為她就是個神經病。這使她很氣憤，所以她將這段感受融入了這首歌曲中。

Oh, she's sweet but a psycho

A little bit psycho

At night she screamin'

"I'm-ma-ma-ma out ma mind"

Oh, she's hot but a psycho

So left but she's right though

At night she screamin'

"I'm-ma-ma-ma out ma mind"

She'll make you curse, but she a blessing

She'll rip your shirt within a second

You'll be coming back, back for seconds

With your plate, you just can't help it

No, no, you'll play along

Let her lead you on, on, on

You'll be saying, "No, no"

Then saying, "Yes, yes, yes

'Cause she messin' with your head

Oh, she's sweet but a psycho

A little bit psycho

At night she screamin'

"I'm-ma-ma-ma out ma mind"

Oh, she's hot but a psycho

So left but she's right though

At night she screamin'

"I'm-ma-ma-ma out ma mind"

Grab a cop gun kinda crazy

She's poison but tasty

Yeah, people say, Run, don't walk away"

Cause she's sweet but a psycho

A little bit psycho

At night she screamin'

"I'm-ma-ma-ma out ma mind"

See, someone said, don't drink her potions

She'll kiss your neck with no emotions

When she's mean, you know you love it

'Cause she tastes so sweet, don't sugar coat it

No, no, you'll play along

Let her lead you on, on, on

You'll be saying, "No (no, no, no, no), no (no, no)"

Then saying, "Yes, yes, yes

'Cause she messin' with your head

Oh, she's sweet but a psycho

A little bit psycho

At night she screamin'

"I'm-ma-ma-ma out ma mind"

Oh, she's hot but a psycho

So left but she's right though

At night she screamin'

"I'm-ma-ma-ma out ma mind"

Grab a cop gun kinda crazy

She's poison but tasty

Yeah, people say, Run, don't walk away"

Cause she's sweet but a psycho

A little bit psycho

At night she screamin'

"I'm-ma-ma-ma out ma mind"

You're just like me, you're out your mind

I know it's strange, we're both the crazy kind

You're tellin' me that I'm insane

Boy, don't pretend that you don't love the pain

Oh, she's sweet but a psycho

A little bit psycho

At night she screamin'

"I'm-ma-ma-ma out ma mind"

Oh, she's hot but a psycho

So left but she's right though

At night she screamin'

"I'm-ma-ma-ma out ma mind"

Grab a cop gun kinda crazy

She's poison but tasty

Yeah, people say, Run, don't walk away"

'Cause she's sweet but a psycho

A little bit psycho

At night she screamin'

"I'm-ma-ma-ma out ma mind"
