facebook know it all
People on Facebook who know nothing but act like they know everything, and they’ll argue about it with anyone, even their own mom.
My cousin said I don’t know anything. I said, 'I know more than you. I read it on Facebook.'
I got into a fight with my neighbor over politics. All because he said I didn’t know what I was talking about.
They asked me if I knew what a recession was. I said, 'I think it’s when people stop buying stuff. I’ll check it later.'
