As bell sounding, fight! (4-4)
I believe the answer is:
ding-dong
I believe this is a double definition.
'as bell sounding' is the first definition.
(ding dong is the sound of a bell)
'fight' is the second definition.
(I've seen this before)
(Other definitions for ding-dong that I've seen before include "Violent exchange - sound of a bell" , "Sound of bell or slang argument" , "Sound of a clapper bell" , "Fight (with hammer and tongs?)" , "Fierce argument (colloq.)" .)
