After church, get a very loud teasing (5)
I believe the answer is:
chaff
'teasing' is the definition.
(thesaurus)
'after church get a very loud' is the wordplay.
'after' is a charade indicator (letters next to each other).
'church' becomes 'ch' (common abbreviation).
'get' is a charade indicator (letters next to each other).
'very loud' becomes 'ff' (musical abbreviation).
'ch'+'a'='cha'
'cha'+'ff' is 'CHAFF'.
(Other definitions for chaff that I've seen before include "Light-hearted banter" , "Refuse from threshing" , "Light banter - husks from corn" , "Shucks" , "Corn-husks separated from the grain" .)
