These are some of the most frustrating people to talk to. They use words without defining what they mean by them. Sometimes they use words that normally have a reasonably accepted definition, but they use them in an unusual way. They pretend to be making all kinds of grand points but they're not actually saying anything. When you question them about this or try to get a defintion out of them, they'll usually say something about you not being open minded enough, or they'll condescendingly explain how not everyone can attain the level of brilliance that they enjoy.

Some oft-abused terms:
Transcend
Order
Chaos
Infinite
Mystical
God
Reality
Spirit
Also Spiritual
Perfection
Time
Truth

Some examples:

I believe that God Transcends the bounds of Space and Time. God exists in the realm of the Spirit.

You must Transcend Reality in order to reach a state of Spirituality.

I believe God is Infinite.

Technically these statements do say something but it doesn't MEAN anything. Newagers frequently do this. They also often suffer from Modern Physics Abuse Syndrome

Example:
Chaos Theory states that the universe is inherently Chaotic and the Uncertainty Principle says that scientists cannot truly know reality. Therefore you must go beyond mere science to experience reality on a spiritual level.
