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.
Someone who goes to great lengths to make sure people stay away from each other.
Look at that person with a full shopping cart! They sure are a Covid Crusader!
A sexual position where the man wears a cape and shouts beware the "winged Crusader " before starting and then shouts things like " Bam! , Pow! , Kapow!" And other such phrases from comics!
Its my birthday and i asked the Mrs to try the winged crusader !
