Could you please tell me what is the meaning of hung up...hung up on you
Madonna - hung up
Every little thing that you say or do
I'm hung up
I'm hung up on you
Waiting for your call
Baby night and day
I'm fed up
I'm tired of waiting on you

Question

Answer

"hung up on you" usually means to be obsessed with that person or madly in love with that person.

However, reading on further from the lyrics of the song, it seems that the romantic feelings for the person which are being given out by the person aren't being returned by the other person and hence he/she is tired/fed up of waiting.
