It is Cocoon slang: [http://archives.real-time.com/pipermail/cocoon-devel/2000-June/000110.html]

Here, you can find people asking for more and more features they are used to:
* WikiAttachments, which could have a good use, can also be used lazily to post word documents
  with discussion material. For this, I would prefer writing a tool to convert Word markup to WikiMarkup :-)
* HTML inside WikiMarkup is __bad__. It will bring back most of the problems we are running from

Just examples, just my opinion. --SantiagoGala
