Good and mad about getting fleeced (5)
I believe the answer is:
stung
'fleeced' is the definition.
(I've seen this in another clue)
'good and mad about' is the wordplay.
'good' becomes 'g' (abbreviation).
'and' means one lot of letters go next to another.
'mad' becomes 'nuts' (I've seen this in another clue).
'about' says the letters should be written in reverse.
'nuts' backwards is 'stun'.
'g' after 'stun' is 'STUNG'.
'getting' acts as a link.
(Other definitions for stung that I've seen before include "Robbed" , "conned" , "like Ray did, perhaps" , "Aroused to impatience or anger" , "piqued" .)
