means Someone with an inflated sense of self-importance who needs constant admiration and lacks empathy for others.

from From Narcissus, the beautiful youth in Greek myth who rejected the nymph Echo's love, then fell for his own reflection in a pool — staring at himself until he wasted away and turned into the flower that bears his name. The word 'narcissism' was coined centuries later, in the late 1800s, by psychologists reaching for his story to describe self-love turned pathological — proof that some myths are really just early case studies.
