Bawls out
I believe the answer is:
scolds
'bawls out' is the definition.
('scold' can be a synonym of 'bawl out')
This is all the clue.
(Other definitions for scolds that I've seen before include "Chides, reprimands" , "Nags - naggers" , "Reprimands, tells off harshly" , "Berates, reproves" , "Tells off, rebukes" .)
