Covert narcissism is narcissism from a unique angle. The internal characteristics are the same as an overt narcissist, but it plays out differently.
Narcissism is not defined in the DSM as the loud and boisterous life of the party. It does not list traits of hitting, cheating, and yelling. 
Rather, NPD is defined as having a grandiose sense of self-importance, requiring excessive admiration, believing that they are special, having a lack of empathy, jealous of others, and arrogant. These traits and others are present in both overt and covert narcissists. How they show up differs. In this podcast, we explore these differences in order to raise awareness of covert narcissism. 
This particular episode addresses the hyper-sensitivity of narcissists and how this displays for both overt and covert narcissists. Overt narcissists react with fear and use intimidation to control of their victim. Covert narcissists react with hurt and victimhood, using guilt and blame to control their victim.
