Mum stuffs chicken for Hercules (2-3)
I believe the answer is:
he-man
'hercules' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'mum stuffs chicken' is the wordplay.
'mum' becomes 'ma' ('ma' can be a synonym of 'mum').
'stuffs' is an insertion indicator.
'chicken' becomes 'hen' (hen is a kind of chicken).
'ma' going inside 'hen' is 'HE-MAN'.
'for' is the link.
Can you help me to learn more?
(Other definitions for he-man that I've seen before include "Masterful male, macho sort" , "Tough guy, doubly male" , "Macho chap" , "Extremely virile male" , "Hunk" .)
