Bring Me Your Cup lyrics by Ub40

The meaning of the song is the that mysterious glorious time when a man is consumed yes, by that visceral physical attraction to a woman but when the spirtual, the purity of love is so high - you aren't thinking about sex - it's her face, her smile that melts your heart like butter sitting before a thousand degrees of heat. You aren't sure if she is yours yet and you can't bear to live your life without her, this creation of God. That friends is what love is about. I have been married to that woman now for 23 years. I can still remember that time. God had to create woman...there is no other way.

The obvious meaning to this song is two people drinking a bottle of wine together, she pops the cork, he fills her glass, they sit and drink until the sunrises.

It seems relevant enough that these two people are lovers from the lyrics abouts his feelings towards her.

The Bottle and cup is a metaphor for sex, he has the bottle, she has the cup (create the image in your head) and he intends to make love to her.

"When you are empty i will fill you up" Meaning that at the climax of their sexual enconter there will be sexual juices.

"I have a thirst only you can satisfy" His sexual desire for her.
"I'm heading home, like a steaming train" He is well on his way to climax.
