Meet, perhaps, without shaking fist (7)
I believe the answer is:
satisfy
'meet' is the definition.
(satisfying is a kind of meeting)
'perhaps without shaking fist' is the wordplay.
'perhaps' becomes 'say'.
'without' is an insertion indicator ('without' can be similar in meaning to 'outside').
'shaking' is an anagram indicator.
'fist' anagrammed gives 'tisf'.
'say' going around 'tisf' is 'SATISFY'.
(Other definitions for satisfy that I've seen before include "Fulfil, a desire or need" , "Content" , "Comply with (condition)" , "Make contented or pleased" , "indulge" .)
