Openings are fine, I usually get canned material and 'Frostalise' it, makin it MY own

I assume it works as it shows it's ME, and it's unique and original.
But let's get down to what I'm here to learn/ get your views on,
In the UK, it's not so.. Americanny, say you do things that Americans can do and pull it off, accent/ actions etc. Here, it's considered WEIRD if you just WHACK out some phrase or sumin. Or that's my area.
What I'm askin is, how do you begin to kino, flirt, and keep the convos going but not TOO serious.
I wanna take a girl out and want her to say to her parents/ or friends;
'' Wow, i went out with Josh today and OMG he's soooo nice! ''
That, and you achieve that through being funny, social etc. Not really into SUPER deep talks, which I'm mainly at. (Good but not THAT good to 'flirt' with)
So tell me, how do i escalate the kino, seduce and keep the convo funny/ interesting as well as show her I'm in for attraction.
One last thing, all this without seeming TOO weird, as remember, I'm just 16.
Cheers guys and Happy xmas

OH one last thing, the female opinion opener, the ones you use in shops, that's right. What do you say when they say, '' Oh god you're not one of those guys asking this as a lame flirty chat up line? '' Along those lines, just wanna be prepared.
