<human>: Can you give me the gist of the text in a nutshell?

Okay so basically at the beginning of the school year I saw a really cute girl in the hallway daily and say funny pick up lines to her for example I said "Is your mom a baker, because you are a cutie pie." I know they are cheesy but that is a point and she laughed at every single one. I kept this going for a really long time but the only problem is I never got her name or number basically not knowing her at all. 

I would really like to take her to prom but I really don't know how to go by it because I barely know her. Also I would like to know the best way to get to know her better. Because she is just my type and I really don't know if she looking for a relationship but I would really like to get to know her better and take her to prom.
<bot>: How should I get to know a girl better that I have been saying funny pick up lines that makes her laugh since the beginning but I do not know her name. And how should I approach her?
