Dupes men with no exception -- female being superior (4,4)
I believe the answer is:
fall guys
'dupes' is the definition.
'men with no exception female being superior' is the wordplay.
'men' becomes 'guys'.
'with no exception female' becomes 'fall' (I can't justify this - if you can you should believe this answer much more).
'being superior' means one lot of letters go next to another (in a down clue, some letters go above others).
'guys' after 'fall' is 'FALL-GUYS'.
Can you help me to learn more?
(Another definition for fall guys that I've seen is " Innocent victims".)
