Film-maker’s expression of disgust after endless kissing (9)
I believe the answer is:
peckinpah
'film-maker's expression' is the definition.
I can't judge whether this definition defines the answer.
'of disgust after endless kissing' is the wordplay.
'of disgust' becomes 'pah' (I am not sure about this - if you are sure you should believe this answer much more).
'after' means one lot of letters go next to another.
'endless' means to remove the last letter.
'kissing' becomes 'pecking' (pecking is a kind of kissing).
'pecking' with its final letter taken off is 'peckin'.
'pah' put after 'peckin' is 'PECKINPAH'.
Can you help me to learn more?
(Another definition for peckinpah that I've seen is " Film director".)
