How do you describe the behavioral patterns of a textbook NPD to someone who is not involved?

We ALL have a little Narcissism in us and it boils down to "ego." Some are just more quiet about it and most of us (thank heavens) are not abusive in nature about it. Most people would understand what a narcissist is, but unfortunately it comes under verbal/physical abuse. Until a psychologist/psychiatrist has diagnosed a person as being a narcissist then it is just arm-chair psychology. It's best to relate to another person the verbal or physical way the person treated you and forget this new age Word "narcissist" because it's confusing.
