Jade's not really into any kind of social events at all, but some girl named Cassidy in one of her classes is telling her about this "epic party" tonight, and she's done all her homework for the week, and she should really try to not be such a loser and get "the college experience" so she figures, why not?
She drinks a shit ton of beer and meets some random douchebag who likes her "nice, round titties" and she has sex with someone other than Beck for the first time in her life. It's worse than anything she ever had with him, including their painfully awkward first time, but that doesn't stop her from sleeping with another gross pervert the weekend after that and another the weekend after that.
It becomes routine for her. During the week, she works diligently and pays attention in her classes, and on the weekend she get shit faced and has sex with strangers.
It makes her temporarily forget that she has virtually nothing meaningful in her life.
