I read a cogent, fairly convincing article by a feminist outlining how "Baby, It's Cold Outside" is actually a feminist manifesto, way ahead of its time: the woman in the song lays out all the social stigma that will be heaped upon her--from her parents, neighbors, aunt, etc.--for drinking, smoking, carousing, etc.--and she ultimately decides to hell with them and does what she wants, knowing it comes with a hefty social price-tag.
