Vulnerable type of male sadly getting nothing (4,4)
I believe the answer is:
lame duck
'vulnerable type' is the definition.
'male sadly getting nothing' is the wordplay.
'sadly' is an anagram indicator.
'getting' is a charade indicator (letters next to each other).
'nothing' becomes 'duck' (I've seen this before**).
'male' is an anagram of 'lame'.
'lame'+'duck'='LAME DUCK'
'of' acts as a link.
(Other definitions for lame duck that I've seen before include "Ineffectual person or thing" , "One who has become powerless" , "Person losing power towards the end of a term of office" , "Person (or bird?) incapacitated by injury etc" , "Person needing help, like limping mallard" .)
