This is a song about a girl I met Who would knock you off your feet but then kick you in the head She looks so normal, she seems fine at first But once you get to know her it's a world of hurt She acting like we're married, in her crazy way Talk's bout commitment and how I have to change She's saving all my money for a rainy day But I wouldn't want to spend it on her anyway I fell in love with a psycho girl No I can't get enough of my psycho girl Once she's in your system, there's nothing you can do So stay away, stay away from my psycho, psycho girl Well no one's ever worked out how she got this way Has she got something to prove, or is she just insane? Another different drama with her everyday It's like living in a freak show that I can't escape She's acting kind of schizo and I don't know why Is it me, or is she just like this all the time? She's got an attitude that changes nearly everyday Her f**ed up world is more than even I can take I fell in love with a psycho girl No I can't get enough of my psycho girl Once she's in your system, there's nothing you can do So stay away, stay away from my psycho, psycho girl She looks so good to me And I can't get her out of my mind She seems like a dream come true But she's a nightmare of the worst kind She keeps me up at nights Going round and round in my head But with a girl like that You know you'd be better off dead I fell in love with a psycho girl No I can't get enough of my psycho girl Once she's in your system, there's nothing you can do So stay away, stay away from my psycho, psycho girl (x2) Psycho, psycho girl (x9)
