A person who is so self-obsessed that they post copious amounts of selfies on their social media with no purpose other than to say "look at me!" They do this in hopes of getting 'likes' and comments telling them they're good looking as that's their way of validating their looks and sense of self(ie)-worth. This narcissism is actually a common practice of someone with low self esteem that tries to overcompensate for their insecurities by posting filtered pictures of themselves hoping to get compliments to feed their ego...as if we don't know that for every one selfie posted there are 10 others deleted.
"I had to un-follow Cassie on instagram because she posts a selfie every five minutes like "look at me on my way to the gym," "now here I am getting my hair done," like I care!"
"If you think that's bad look at Kim Kardashian's - now she is selfie-obsessed, on instagram and real life!"
