spelling flame

spelling flame n.   [Usenet] A posting ostentatiously
   correcting a previous article's spelling as a way of casting scorn
   on the point the article was trying to make, instead of actually
   responding to that point (compare {dictionary flame}).  Of
   course, people who are more than usually slovenly spellers are
   prone to think *any* correction is a spelling flame.  It's an
   amusing comment on human nature that spelling flames themselves
   often contain spelling errors.
