Gather children, let me tell you the story about SA. Sour Apple is that girl in your class who you didn't even know was in your class to begin with. She is plain, boring and doesn't seem to give a damn about anyone around her. You're at party and every hot girl there is either too good for you to approach her or you're scared of that buff guy around her who you think is her boyfriend. Life sucks now because your plan of hooking up with any hot chick is crumbling to nothing. But then wait! That boring unattractive girl is sitting right across from you with a drink in her hand; looking weirdly around the room. You talk to her and then ten minutes later, you find out you like the same band and other crap. Things go great and you end up at her place. "Well that escalated quickly" is what you're gonna think but let's just give you the benefit of the doubt and your charm was 100% spot on. Then you realise that this girl who seemed so undesirable on the outside was actually super cool and sexy on in the inside. You no longer see her as what she portrays to the outside world but you love her for she really is.
