It means that you are either been miss ranked, or are posting information that is not correct. Such as being able to fly or fire balls at a few words being said. It basicly means just look into the real meaning of Magick and avoid joining in "fluffy" conversations on the forums and chat
just an add on with the description above, you're basically being called a 'Fluffy Bunny' which is a demeaning term people in the craft tend to use to describe people who joined because it seemed cool, like if someone saw The Craft or Practical Magic [btw i love that movie] and figured since the main characters were cool they'd start acting like them, basing their knowledge of wicca off pop culture views. not saying you are, just if you're called that again they're calling you out.
