So fired without hesitation? (4,1,4)
I believe the answer is:
like a shot
'without hesitation?' is the definition.
(I've seen this before)
'so fired' is the wordplay.
I cannot really understand how this works, but
'so' could be 'as' (e.g. phrases like 'not as tall' and 'not so tall') and 'as' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for like a shot that I've seen before include "'Pronto!'" , "What serious drinkers do" , "looking round, in field event?" , "What tequila drinkers might do" , "enthusiastically?" .)
