Type of internet troll, focused on trolling anime and manga posts on internet forums.
This kind of person has strong knowedge of Japanese culture (as a matter of fact he will be probably Japanese as well) and has compiled tons of useless data about manga typos, anime glitches or mistakes. He will use this information to disturb another unprepared otakus.
