One question only - would you want to fvck this girl?
If yes, there is a good chance she might want to as well.
Next time come up to her, and say something along the lines of "Oh, you are done!" , grab her in your arms and give her the best kiss she's ever had.
First, the whole school will go nuts. Second, you win.
If she is ugly.. just say "Hey, i know you really wanna roll around with me, but you gotta get in line girl
", if she persists, say "Really, get over it babe".
OK, time to pull out a memory chest.
There was this girl i really liked in 9th grade. She was new, and even came up to me with her friend to "test me out" and see if we could hang, but i was such a "playa" that i sat at the table all cool, didnt even talk to them... wow i was "amazing"... so basically she moved on (started going out with some other guy) and i still was "in love" with her.
Now she had a step sister, who just woudnt fvcking gimme a break. In gym class, i had the tendensy to blame girls for sucking at sports.. when they were the reasons my team was losing. (i hate losing at sports). And so one day she thought it was too much and walked up to me and started talking major ****, in the middle of the gym class. She started hitting me, trying to kick me in my balls, but i was like "fvck leave me alone" ... just defending myself while she was having fun
.... during all this time the whole classs just sits there and the teacher just watches.. without doign a damn thing...
so as she is done, she starts walking away.. and finally delivers the final blow by saying "My sister would never go out with you!"..
Now, sad story? Hah, i dont think so anymore.. Funny thing is the girl who i liked went out with a lot of guys for a long time in HS, but every single one of them told me "she was g a y" meaning she didnt want ANY sexual stuff..
But yeah man, live and learn, go take care of business.
