facebook scientist
Someone who thinks they're an expert just because they read about it on Facebook. They know everything from climate change to alien conspiracies, even though they don’t know what a real scientist is.
"I know everything about global warming because I read it on Facebook!", @FBExpert4Life
"You think you’re smart? I know more because I watch Facebook all day!", @FBKnowledgeGod
"I got my news from Facebook. That’s better than the real news!", @FakeNewsFanatic"
