facebook hater
They’re the kind of person who lives on Facebook but would rather like a post about a dog eating a sock than your whole life.
You post a photo of your vacation. They comment 'That's nice.' and like a post about someone's dog eating a sock.
You tag them in a group chat. They say 'I don’t know what that is.'
You send them a message saying 'I posted something cool.' They reply with 'I didn’t see it.'
