look up any word, like bukkake:
 
1.
A facebook user, or a user of virtually any other social internet forum, who spends a great amount of time finding random people to correct and criticize on various intellectual issues. Usually well-read and articulate. Almost like a troll, but too snobby and brainy to be completely classified as one.
Is that a troll? No, it's a forum crusader.
