I know how Matt hates the word spiritual. i think I've come up with exact definition for it.
We have to look at the base word on that word. Spirit, some people refer that as some non material blahblah, but on other hand strong alcohols are referred as spirits.
So combining those two words loose handedly, spiritual is a human who is under heavy influence mumbling something utter nonsense. Spiritualism = belief that alcohol causes one to be totally wasted when digested huge amounts?
Hope you had fun reading this :D
