Satisfied after fruit drop down (7)
I believe the answer is:
plummet
'drop down' is the definition.
(thesaurus)
'satisfied after fruit' is the wordplay.
'satisfied' becomes 'met' ('meet' can be a synonym of 'satisfy').
'after' is a charade indicator (letters next to each other).
'fruit' becomes 'plum' (plum is a kind of fruit).
'met' after 'plum' is 'PLUMMET'.
(Other definitions for plummet that I've seen before include "Drop at speed" , "Fall headlong" , "Fall rapidly" , "Plunge headlong" , "fall sharply" .)
