I was curious about this definition and found an article on Flying Monkeys Denied.com.
What is a Narcopath?
Above and beyond traditional definitions for what the Baby Boomers and WWII Generation grew up calling a “Megalomaniac” is a new definition of a public figure as well. A new classification of “Narcopath” has also emerged to define a “Narcissistic Sociopath” separately identifiable from the terms “Dark Triad” or “Malignant Narcissist”.
Understanding Narcopathy is an emergent academic research discipline evolving in part due to the widespread epidemic of NPD and ASPD sweeping not only across the United States but also globally. Considered emotional terrorists, Narcopaths typically take great pleasure in being in positions of power — places they should never be due to their inability to reign in capricious greed.
Because they are oftentimes temperamental, reckless, and red-faced, when they attain positions of power, they cannot seem to resist the urge to behave selfishly. Frighteningly predictable, they are unable to control their own impulses to behave in ways that do nothing but promote fear or discord in their own lives.
As a result, the people who know them best tend to dread having to spend time around them. Why? Because no one who is not masochistic seldom enjoys being lied to, brutalized, dressed down with zero input of constructive criticism, manipulated, taunted, ridiculed, laughed at, or antagonized.
Like small children or petulant teenagers behaving with an unjustified and/or illegal sense of entitlement, the Narcopath cannot resist the urge to make malevolent mischief no matter what the day or situation.
