Gossip movie

For a class project, three self absorbed college students decide to do their project on gossip to track its growth. But, first they need some gossip so one night at a nightclub, they spot a guy (Jackson) and a girl (Hudson) making out before the girl passes out. Around the campus the girl is known for not giving out. The three decide to use that as their base and mix it into her boyfriend raping her when she was passed out. The gossip gets spread to the girl who only remembers passing out at the club. One of her friends suggest that maybe her boyfriend raped her.
