MEANING: A young person or one with a youthful cast of mind, gentle and loving, artistic and insightful. If a girl, somewhat tomboyish, if a boy, then somewhat feminine. This person could be emotionally vulnerable and needs affection.
REVERSED MEANING: A trivial and spoilt person, one who manipulates others' feelings. Perhaps this person lives in a dream world.
I think this description does me pretty good justice. And as you've noticed, the "cups" do rather tend to be just "alcohol".
