Boozer drinking hooch finally fired (4)
I believe the answer is:
shot
'fired' is the definition.
(shooting is a kind of firing)
'boozer drinking hooch finally' is the wordplay.
'boozer' becomes 'sot' (I've seen this in another clue).
'drinking' indicates putting letters inside (inserted letters are consumed or drunk).
'finally' indicates one should take the final letters.
The final letter of 'hooch' is 'h'.
'sot' going around 'h' is 'SHOT'.
(Other definitions for shot that I've seen before include "Firing of a gun" , "Fired; turn" , "Darted" , "Short drink; attempt" , "Ruined; photograph" .)
