In France, the loud call is to make a verbal attack (4,3)
I believe the answer is:
lash out
'attack' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for lash out that I've seen before include "React aggressively" , "unprovoked attack" , "Attack with blows or words - using whip?" , "spend a fortune" , "fight vigorously" .)
