Male on the farm and servant run amok (7)
I believe the answer is:
rampage
'run amok' is the definition.
(I've seen this before)
'male on the farm and servant' is the wordplay.
'male on the farm' becomes 'ram' (I've seen this in another clue).
'and' is a charade indicator (letters next to each other).
'servant' becomes 'page' (I've seen this before).
'ram'+'page'='RAMPAGE'
(Other definitions for rampage that I've seen before include "Fury" , "Uncontrolled rush" , "Violent rush" , "Frenzy" , "Rush around violently and uncontrollably" .)
