I Fell in Love With Someone I Shouldn't Have

I fell in love with someone that, that I shouldn't have
I gave my heart to someone that, that I shouldn't have
Hey, you waste of space, don't show your face again
Or I'll mess you up and tell all your friends
I fell in love with someone that, that I shouldn't have, yeah

Waste my time on someone that, that I shouldn't have
I put my trust in someone that, that I shouldn't have
Went and let them in and they trashed the place
So I set fire to his car, you should've seen his face
You went and fucked with someone that, that you shouldn't have

'Cause if I were you, I'd be running away
She is a girl with a temper and something to say
And her heart's not a toy, it's a hand grenade
They say that love is a war and you'll never be saved
You better run, 'cause she's an atom bomb

I got lost in someone that, that I shouldn't have
Got in too deep with someone that, that I shouldn't have
I know you said that I'm bad, you wanna punish me
Won't get on my knees and call you d-d-daddy
You took everything I had when you shouldn't have

'Cause if I were you, I'd be running away
She is a girl with a temper and something to say
And her heart's not a toy, it's a hand grenade
They say that love is a war and you'll never be saved
If I were you, I'd be running away
She is a girl with a temper and something to say
You better run, 'cause she's an atom bomb
(You better run, 'cause she's an atom bomb)

She don't need you now
She don't need you now (I'm nothing but a teenage runaway)
She don't need you now (I'm just a bad influence you want nothing to do with)
She don't need you now (bad influence you want nothing to do with)
