'hostility' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'i shall repeatedly include women's' is the wordplay.
'i shall' becomes 'ill' (contraction of 'I will').
'repeatedly' shows that letters should be duplicated.
'include' indicates putting letters inside.
'women' becomes 'w' (standard abbreviation).
'ill' duplicated is 'illill'.
'illill' enclosing 'w' is 'ILLWILL'.
