“Baby, It’s Cold Outside” was written by Frank Loesser in 1944 as a duet to be sung with his wife (wikipedia)
It has been performed many times since and by different artists and is generally viewed as a humorous song involving a conversation between a man and a woman. She wants to go home but he wants her to stay
While originally interpreted as a scene of gentle seduction, with the woman secretly wanting to stay and only putting up token resistance when the man tries to persuade her, the lyrics are capable of a more sinister interpretation. For example – “Hey, what’s in this drink” – suggesting that he has tried to drug her.
This version of the song cleverly reverses the roles of the man and the woman, it being the man who wants to leave and the woman who is trying all in her power to make him stay
