Disgusting row about old male (7)
I believe the answer is:
noisome
'disgusting' is the definition.
(I've seen this before)
'row about old male' is the wordplay.
'row' becomes 'noise' (row can mean a disturbance or noise).
'about' is an insertion indicator.
'old' becomes 'o' (abbreviation).
'male' becomes 'm' (common abbreviation).
'o'+'m'='om'
'noise' enclosing 'om' is 'NOISOME'.
(Other definitions for noisome that I've seen before include "Disgusting to sight or smell" , "Repugnant" , "Humming" , "Nasty" , "Evil-smelling, objectionable (7)" .)
