Protest defeat in shouting match? (6)
I believe the answer is:
outcry
'protest' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for outcry that I've seen before include "A strong protest, often public" , "indignation" , "Public show of anger" , "Furore, uproar" , "A storm of protest" .)
