Drink editor slugged (7)
I believe the answer is:
punched
'slugged' is the definition.
(slug can mean to hit or punch)
'drink editor' is the wordplay.
'drink' becomes 'punch' (punch is an alcoholic drink).
'editor' becomes 'ed' (abbreviation).
'punch'+'ed'='PUNCHED'
(Other definitions for punched that I've seen before include "Hit with a fist" , "Thumped" , "Belted" .)
