Rows typically involve everyone rudely shouting at first (5)
I believe the answer is:
tiers
'rows' is the definition.
(tier is a kind of row)
'typically involve everyone rudely shouting at first' is the wordplay.
'at first' says to take the initial letters.
The initial letters of 'typically involve everyone rudely shouting' is 'TIERS'.
(Other definitions for tiers that I've seen before include "Layers, levels" , "drawers?" , "Binders" , "aprons for kids" , "Rows; levels" .)
