@Spectrewoot,
My best guess, is an hourglass...
Does it means something about having an hourglass figure...Like a moon (women) too cold to show your figure... But better off hot like the sun (talking about women's figures on a beach or something...)
That is my best guess...
But it does not sound right....and is grabbing too many straws...I don't know the correlation between Women's figures and the moon...
