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

She is extremely bitchy when you're in an argument, she always thinks she is right, even when she isn't. Doesn't care about much, but herself, very hormonal, and into boys alot. Gets jealous sometimes, can get annoyed quickly if you say something bad about her. Very rude and always has to have it her way. Likes surprises. She's generally a really nice person, but you're in trouble if she doesn't like you/ you have got into an argument. Very loud and ongoing. Likes to be heard/ known. Not very mature for her age, doesn't see things in other people's shoes, hence her thinking she is right all the time. Doesn't like it when people explain it or repeat things, although she is very repetitive herself. Quite popular, and very pretty, although she doesn't see it.
Person 1: I'm so upset :'(

Person 2: Why?

Person 1: Because I'm in an argument with someone!

Person 2: Unlucky. Is it Marnie who you're in an argument with?

Person 1: Yeah.

Person 2: God help you!

To be soo drunk that you kill off a great party.

Marnie'd > Mortal > Drunk

The party ceases due to a certain someone.
"Brah she's absolutely marnie'd the night!"

"Mate I was so marnie'd on the weekend!"

"Did you see that girl who marnie'd the night?"
