To me it seems like it's just a new tactic for barbies to let guys know, "heelllooo, if im kissing a girl, then obviously im willing to kiss you", or tease guys and attract in genearal. I think alot of that shit comes from the porn industry and pop music, lets face it, bi is in. So just like the advertising media standardizes beauty, so goes the sexuality, but i think there point behind it is to promote premiscuis youth, and generally demoralize them. Not that i think bi sexuality is amoral, but the majority of this country does, and its medias job is to be the fucking devil. Maybe its her. Or, or, maybe its Mabeline. A pop culture phenomenon?
