Exposed blubber creates a widespread show of disapproval (6)
I believe the answer is:
outcry
'a widespread show of disapproval' is the definition.
(outcry is mass disapproval)
'exposed blubber' is the wordplay.
'exposed' becomes 'out' (out on display).
'blubber' becomes 'cry' (to blubber is to cry uncontrollably).
'out'+'cry'='OUTCRY'
'creates' acts as a link.
(Other definitions for outcry that I've seen before include "Widespread protest - clamour" , "Exclamations of opposition" , "Exclamation - clamour" , "Exclamation, shout" , "Strong expression of public disapproval or anger" .)
