Debauched feature of corgi a sticking-point (9)
I believe the answer is:
orgiastic
'debauched' is the definition.
(I've seen this before)
'feature of corgi a sticking-point' is the wordplay.
'feature of' indicates the answer is hidden within the clue.
'ORGIASTIC' is hidden in the letters of 'corgi a sticking point'.
(Other definitions for orgiastic that I've seen before include "Debauched" , "become overindulgent" , "Licentious" .)
