Complete swine in cad: sort she messed around (6-3-5)
I believe the answer is:
across-the-board
'complete' is the definition.
(thesaurus)
'swine in cad sort she messed around' is the wordplay.
'swine' becomes 'boar' (male pig).
'in' is an insertion indicator.
'messed around' indicates an anagram (I've seen 'messing around' mean this).
'cad'+'sort'+'she'='cadsortshe'
'cadsortshe' is an anagram of 'acrossthed'.
'boar' placed inside 'acrossthed' is 'ACROSS-THE-BOARD'.
(Other definitions for across-the-board that I've seen before include "generally" , "How men may move" , "General" .)
