Don't retaliate when badgers re-enter the hutch, OK! (4,3,5,5)
I believe the answer is:
turn the other cheek
'don't retaliate' is the definition.
(I've seen this before)
'badgers re-enter the hutch ok' is the wordplay.
'badgers' is an anagram indicator (I've seen 'badger' mean this (the letters must be badgered or bothered)).
're'+'enter'+'the'+'hutch'+'ok'='reenterthehutchok'
'reenterthehutchok' anagrammed gives 'TURN THE OTHER CHEEK'.
'when' acts as a link.
(Other definitions for turn the other cheek that I've seen before include "Don't retaliate" , "just wiggle while mooning" .)
