I’m going to assume that you are in high school right now, and if you’re not then I’m contacting the FBI because you are a pervert (kidding). Just be sure to check your state’s age of consent before you hit on the young girls.
High school girls are a little different from ones in college and beyond. They are not yet emotionally developed so you will be unable to connect with them by using complicated or involved routines. They take cues from who they should like through their friends, so if her friends don’t think you are cool then you have absolutely no chance. If it happens that you meet her without her friends around but she needs their validation, you will not get anywhere. She’ll just freeze up and not talk to you.
On the other hand if she is the independent type without a lot of friends, then you can hit on her like you normally would an older girl. It comes down to if she is the popular cliquey type or not. If she is then your job is harder; otherwise it’s easier.
The best way to flirt with high school girls is to establish fast interest and then make it seem like you don’t like her. For some reason this formula is like crack to the high school girl. You want to get off the on the right foot by making her laugh or having a solid first conversation, then follow them with being aloof and teasing her mercifully. The more she thinks you don’t like her, the more she will like you.
This strategy sometimes works on older chicks, but it’s much more deadly when flirting with high school girls. You have to be that guy that simply doesn’t give a fuck but is cool and mostly friendly around her friends. There will be a moment when it’s obvious she likes you because she keeps asking you questions. That’s when you get her isolated and go for the kill, usually after playing the text messaging game.
Meeting high school girls is easy if you are in high school (obviously), but if you’re not in high school then your best bet is the mall on the weekends, especially the food court. The food court is like home base for the high school crowd and you will have to approach with something like, “You guys go to ________ high school right?” If all else fails then you can always hit on your teacher.
Flirting and building attraction is crucial when it comes to helping the girl decide that she wants to sleep with you. Before I knew how attraction really worked, I’d approach a girl and talk about boring topics such as work or her favorite movies, and then she would politely excuse herself from the conversation only a couple minutes into it. But now I know better. When you talk about more interesting topics, she sees you as more interesting. It’s as simple as that. With a couple additional techniques, the “interesting” is turned into strong attraction.
