Social Nancy

A social Nancy is a negative online Nancy.
A person who doesn't necessarily post negative things often. A person who scrolls past your positive or normal posts, always. But reacts to posts they choose to be negative and accuse you of being miserable and wrong.

Negative online Nancy's choose to ONLY give your social media account attention; likes and comments- when it's negative because it serves them a purpose to preach and be "right".

"I didn't even know you were on my friends list because of how you never like or comment on any of my posts. You're being a Social Nancy right now tho."
