I've always found the easiest way to describe "Pagan" to someone is to say that it is pretty much anything that isn't Christian, Muslim or Buddhist, at least, that is how the whole thing seems to me. People at least think you aren't a complete lunatic if you tell them you are one of the "Big Three", and you can even get away with telling people you follow Native American beliefs and not have them wave garlic at you.
Anything else, though, and the "normal" people will start moving away from you in a crowded room. And I like it that way!
