Bully initially scoffed getting thrashed (6)
I believe the answer is:
beaten
'thrashed' is the definition.
('beat' can be a synonym of 'thrash')
'bully initially scoffed getting' is the wordplay.
'initially' indicates taking the first letters.
'scoffed' becomes 'eaten' (I've seen this before).
'getting' says to put letters next to each other.
The first letter of 'bully' is 'b'.
'b'+'eaten'='BEATEN'
(Other definitions for beaten that I've seen before include "Formed or made thin by hammering" , "Worsted" , "Defeated or mixed vigorously" , "Hammered" , "Defeated or overcome" .)
