Narcissistic supply refers to the attention, admiration, and validation that narcissists seek from others in order to maintain their inflated self-image and sense of self-importance. This "supply" can come in various forms, such as compliments, praise, adoration, or even fear and submission from others. Narcissists often engage in manipulative and controlling behaviors to secure this supply, using others as a means to boost their own ego and maintain their self-esteem.| Simply Psychology
