Pay attention my little highschool friend, these tips will serve well in college.
First off the number one thing to know young grasshoppa is always, always, ALWAYS stay casual. It's all about being chill and not over doin' ANYTHING.
1) start texting casually, just talking about the day and shit but BE CAREFUL......too much could mean friend zone FA SHO. Remember, its all about being casual. Too much and you're best friends but not enough and she'll still be interested............
2) find a party one night and invite her over, DRINK AND RAGE (<----------PRETTY FUCKIN IMPORTANT unless she's fiending for it and you can pull it off sober) , start giving her some shit for some of the text convo's you had (jokingly and flirting of course) or some funny shit she does at a party or whatever. IDK why, and all of NS can quote me on this, but girls like guys who are going to give them shit or just mess around with them casually. Other guys who aren't getting laid like to say that girls like all the guys who are dicks or straight assholes but what they don't realize is that most of the time its casual and fun unless its like some jersey shore shit and its Guid-o status. Then they have a point. But generally It's more fun and usually leads to something better...........
3) if step one and step two were performed correctly, you should have a pretty good understanding of the situation and whether or not to fire and at that point, SO NOW its just time to step up to the plate. I dig you, I want you, you look beautiful tonight, wanna see how I changed up my room posters? etc. and If you played your cards right, she might just be all over you
ALSO, coming from personal experience, it doesn't matter if its a rager or like 2-3 of your friends chillin. as long as you're talking to her and workin' the game, your money. Builds up the pussy if you ain't gettin laid that exact night.
GO FORTH AND PROCREATE MA BOY
