From the Q-Man English Dictionary--
Spirituality, n.
1. A more polite, modern, PC, and slightly esoteric way of saying "religion"
2. A word for religion from someone who is too lazy to practice it or go to services (e.g."No, I don't go to Sunday Mass, I'm not really 'religious', more 'spiritual', please pass the bong")
3. Something involving crystals, wicca, drum circles, and other crazy hippie shit
Pretty much sums it up. Although you could add something like:
4. A manifestation of normal human narcissism and primal fears masquerading as something noble.
Devious, treacherous, murderous, neanderthal, sub-human of the West.
