Exult as farm animal eats pounds (5)
I believe the answer is:
gloat
'exult' is the definition.
(I've seen this in another clue)
'farm animal eats pounds' is the wordplay.
'farm animal' becomes 'goat' (I've seen this in another clue).
'eats' means one lot of letters goes inside another.
'pounds' becomes 'L' (L can represent the monetary pound).
'goat' placed around 'l' is 'GLOAT'.
'as' is the link.
(Other definitions for gloat that I've seen before include "Express triumphant self-satisfaction" , "Look like the cat who got the cream" , "Dwell on with self-satisfaction" , "Take malicious satisfaction" , "Be full of malicious delight" .)
