Crab:
A strange creature with weak body armour and has a funny walk. It looks dangerous because it has weapons on the end of its foremost arms but these can easily be overcome by common sense. It can't read, write or talk properly because it is a crustacean....

Does that sound anything like the vast majority of authors for the definition of "Crab", and the ones to whom they apply their definitions??
Lol @ the gang war going on on UD. Fighting it out using dictionary definitions, real tough!

Of course, I have full respect for the actual crabs out there under rocks and in the sea and such.
