The term "narcissist's last trick" is not a commonly used or recognized psychological concept. It's possible that you are referring to the idea that narcissists often employ various manipulative tactics or "tricks" to maintain control and power over others in their relationships.
Narcissists are known for their cunning and manipulative behavior, and they can continue to use these tactics until the end of a relationship or interaction. Some common manipulative tricks employed by narcissists include:
Gaslighting: The narcissist distorts the truth, denies their actions, or undermines the other person's perception of reality, causing them to question their own sanity or memory.
Hoovering: After discarding someone, the narcissist may attempt to "hoover" them back into the relationship by using charm, promises, or guilt-tripping.
Triangulation: The narcissist involves a third person to create jealousy or insecurity in the relationship, fostering competition for their attention.
Love-Bombing: In the early stages of a relationship or reconciliation, the narcissist overwhelms the other person with affection, gifts, and attention to gain control and adoration.
Silent Treatment: The narcissist uses the silent treatment as a form of punishment and control, giving the other person the cold shoulder and ignoring their attempts to communicate.
Blame-Shifting: The narcissist avoids taking responsibility for their actions by shifting the blame onto others, making them the scapegoat for any problems or issues.
Smear Campaigns: When feeling threatened or exposed, the narcissist may launch a smear campaign to tarnish the reputation of the person they perceive as a threat.
It's important to recognize these manipulative behaviors and protect yourself from the harm they can cause. If you are dealing with a narcissistic individual, setting healthy boundaries, seeking support from loved ones, and potentially consulting a mental health professional can be beneficial in handling the situation and protecting your well-being.
