I think this one works as an escalator/closer.
First just bring the conversation in on movies, scary movies and if she asks you about any movies you have seen, take that as an ioi and say this.

PUA: hmm i've seen the ring (we all know that one don't we?)
HB: omg that is scary/ its boring / havent seen it blabla blahh
PUA: no stupid not the movie(smile), i've seen the tape (dead serious), i only got about 5 days left. so if you think i'm hitting on you think again, i'm just trying to get you to watch it so i don't have to die.

(remember eye contact and a serious look on your face)

i made it up myself, is it any good?
any changes to it?

Hmm. Field test it, I think you'll have to alter it a bit. Even in this case talk of death and dying is a touchy subject. Make sure you say the last bit with a smile and then maybe a hug. Not sure it would lead to excalation or closing though.

It depends on how you deliver it. I can see this one work like a charm if delivered correctly and to crash and burn if it is delivered in a bad way...

Point blank denying the fact that you're hitting on her when the thought hasn't even crossed her mind... if she hasn't assumed it already, she definately will after you say that. The whole "don't worry, I'm not hitting on you" thing just sets off alarm bells in her head and she'll know for a fact you're hitting on her because, if you weren't, you wouldn't exactly be concerned if she thought you were - would you?

However, that doesn't mean it won't work. It'll get her laughing, but the way you move forward afterwards is important. You can't just keep up the fluff talk and work your way to a close, cos you've just planted the idea in her head that you're gonna try to get her number or whatever. So the longer you leave it, the more it looks like you're trying to figure out how to broach the subject. Not good shit. So, personally, right after this I'd be like "yeah right, of course I'm hitting on you... I mean, I've only got 5 days left!" or something to that effect. Little roleplay type things like this are quite fun, and she'll get a kick outta it.
