I don't like to admit it, but I'm in the same boat as you. I've heard NN used, depending on the context, to refer to prohibition of:
1) Throttling sites the ISP doesn't like.
2) Any kind of penalty for heavier users.
3) Charging for access to special pipes that are faster, when both sides want to pay a premium for speed and reliability.
Unless I ask directly I have a hard time discerning what someone means by NN, and even then I don't know how well it maps to what new regulations will actually do.
Edit: Another attempt at clarifying first sentence.
