Pack and go (4)
I believe the answer is:
gang
I believe this is a double definition.
'pack' is the first definition.
('gang' can be a synonym of 'pack')
'go' is the second definition.
(thesaurus)
'and' is the link.
(Other definitions for gang that I've seen before include "set of tools" , "crowd" , "Association of criminals" , "Crew, band" , "Group of friends, criminals" .)
