Packed and shaved, getting the middle bit twice (6)
I believe the answer is:
filled
'packed' is the definition.
(thesaurus)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for filled that I've seen before include "Glutted" , "Occupied the whole of" , "Topped up" , "Repleted, satiated" .)
