1. Peter: "Why won't Mary stop posting e-meme pictures she didn't even create herself?"

Paul: "Because she's an e-narcissist."

2. Peter: "Why does Mary keep posting? It seems she just posts whatever she sees happening around her all the time, just so she can post something."

Paul: "Who cares? She's a horrible person anyway... oh, and she's an e-narcissist."
