Hi, my booklet from the CD explains: Creme de la Creme! Oh moon!
It´s an expression of admiration for a beautiful woman.
The song was composed by Monir el Wisimi fo the Reda Troupe (that time with Raqia HAssan).
I have found a sample to listen to:

If our native arabic speakers scroll down at this side to the CD AMAR 14, it´s the 7th song; you can listen right away to the chorus of this song.
Happy hips, Tahira
