1.
Someone who posts on Facebook about all their ideals and causes....without doing any real work. They find a cliche post that someone else wrote and re-posts it, thinking they're part of the fight. But their post gets lost in Facebook's "previous post limbo", never to be seen again by anyone. They can be a part of millions of different causes without lifting a finger (other than their mouse clicking finger). Posers.
Did you see Mary's Facebook Warrior flavor of the week? It's called CABWHEL... I don't know, it has something to do with Cousins against Big Wheels or something.

Someone who constantly sticks their nose in other people's Facebook business with the intention of creating drama, threatening to come to the other person so that they can "handle it", and then never actually showing up to fight and settle the situation.

"Yeah he's a right Facebook warrior."
