Polish local back on the game (3,2)
I believe the answer is:
rub up
'polish' is the definition.
(thesaurus)
'local back on the game' is the wordplay.
'local' becomes 'pub' (I've seen this before).
'back' shows that the letters should be reversed in order.
'on' is a charade indicator (letters next to each other).
'the game' becomes 'ru' (rugby union).
'pub' written backwards gives 'bup'.
'bup' put after 'ru' is 'RUB UP'.
(Other definitions for rub up that I've seen before include "Polish" , "shine" .)
