Crab meat (4)
I believe the answer is:
beef
I believe this clue is a double definition.
'crab' is the first definition.
(thesaurus)
'meat' is the second definition.
(beef is a kind of meat)
(Other definitions for beef that I've seen before include "Meat - complaint" , "Grumble - muscle" , "Brawn; complaint" , "Strength - grievance" , "Bovine flesh" .)
