facebook doctor
A Facebook Doctor is a conspiracy theorist who thinks they're a doctor because they saw a post about it. They ignore real doctors and think masks are fake. They live in a fantasy world where they're always right and everyone else is dumb.
'The government is hiding the cure for the flu. I found it on Facebook.'
'Wearing a mask? That’s a scam. I read it on a Facebook group.'
'You’re not sick. The doctor is in on it. I know this because I’ve seen it on Facebook.'
