Marnie- a beautiful girl, who is also fiercely intelligent, but slightly, endearingly vulnerable. She generally can be seen wandering around at odd hours, wearing weird clothes and with a lad on her arm, hanging onto her every word. Basically she is exceedingly charming but watch out!
eg -wow look at her smile
-no be careful she'll break your heart! she's a Marnie

- well yeah, I'm heartbroken but I was lucky, she was a real Marnie
-that's what Marnie's are like i guess
