body: Is it legal to use or reference a part of a story / series like saying, "Studs are super-saiyan dykes"?
  
  
  Would the studio that owns DBZ have a way to sue for using "super-saiyan" by claiming it was defamation, diluting their brand, etc., since it is a special term which many anime fans would recognized from the franchise?
