Shame about boring argument (9)
I believe the answer is:
disrepute
'shame' is the definition.
(thesaurus)
'about boring argument' is the wordplay.
'about' becomes 're' ('re' means regarding or about).
'boring' is an insertion indicator (to bore something can mean to drill into it).
'argument' becomes 'dispute' (I've seen this in another clue).
're' placed within 'dispute' is 'DISREPUTE'.
(Other definitions for disrepute that I've seen before include "get a bad name" , "Ill fame" , "Ignominy" , "State of being held in low public esteem" .)
