Facebook Crusader
A Facebook Crusader is someone who fights on Facebook like it's a war. They argue with everyone, use Google and Wikipedia to back up their points, and make you feel stupid if you don’t agree.
They write, 'Your post is wrong. Let me check Google.'
You say, 'I think that’s cool.' They say, 'Cool? That’s not even a real word.'
They argue with you for 10 minutes just because you said 'y’all' wrong.
