Second line battered and bullied (10)
I believe the answer is:
browbeaten
'bullied' is the definition.
('browbeat' can be a synonym of 'bully')
'second line battered' is the wordplay.
'second' becomes 'b' (B can mean second eg B-side).
'line' becomes 'row' (a row or line of things).
'battered' becomes 'beaten' (synonyms).
'b'+'row'+'beaten'='BROWBEATEN'
'and' acts as a link.
(Other definitions for browbeaten that I've seen before include "Bullied" , "Intimidated" .)
