the only reason why i dont think its AS big a deal, is because she flashed a group of people,
group mentality of just getting cought up in the moment and her sexuality was not fixated on another person. it was more of a selfish attention whoreish thing on her part than giving her love/respect/care/affection to an individual.
now if the title was "GF took dude she thought was hot into the back room and showed him her tits", that would be fucked up.
the difference is one is just being a slutty drunk college girl, and the other is being at risk for cheating
