Well, first you have to give her a few drinks, maybe even slip a lil' something something in one of them too. Then it's basically straight forward after that, as she'll most likely be all over you. Then just made a few moves, get her in bed, and BAM. It'll be done before you know it.
By the way, that was a joke, so don't take it seriously kid.
This girl obviously likes you, I mean laughing and calling you names? That's got to be a good thing.
The question is... do you like her?
If you do, just go ask her... she'll admire your confidence.
