Attacked the twit taking the girl back (8)
I believe the answer is:
assailed
'attacked' is the definition.
('assail' can be a synonym of 'attack')
'the twit taking the girl back' is the wordplay.
'the twit' becomes 'ass' (I've seen this in another clue).
'taking the girl back' becomes 'ailed' (I can't justify this - if you can you should give a lot more credence to this answer).
'ass'+'ailed'='ASSAILED'
Can you help me to learn more?
(Other definitions for assailed that I've seen before include "Went for" , "Attacked, lashed out" , "became aggressive" , "Violently attacked" , "charged" .)
