To narcissize is to use all your manipulation tools for
the end goal for the end goal of receiving
narcissistic/megamanic supply. This includes hoovering, triangulation, gaslighting, breadcrumbing, future faking, scapegoating, love-bombing and then devaluing, psychological projection, boundary erasing,
schadenfreude, and all the other tactics used by both covert and grandiose/overt narcissists. The person being narcissised, the narcissizee, is often either a codependent or echoist.
