What is the meaning of the song "Call you after the party is over" by Billie Eilish mean?

A woman that I know sent my friend a video over the internet called "Call you after the party is over. The person then stopped talking to him. I listened to the song myself and was confused by the video, lyrics and music itself lol.
Why is she crying in the video? What do the lyrics truly mean? What is the overall sentiment of the song and why would someone send it to them and stop talking to them?
