I think in this song there is a drunk girl, or maybe a girl that just wants him because he's famous who's approaching him to have sex, but he doesn't want to "you know you lack originality I don't drop my pants that easily so baby, just get away from me". He's saying that all the girls dream of him and she's not going to get him that easily, and he's not stupid enough to fall for her.
