One may go off meat, say, eating wodges regularly (6,3)
I believe the answer is:
powder keg
'one may go off' is the definition.
I can't judge whether this defines the answer.
'meat say eating wodges regularly' is the wordplay.
'meat' becomes 'pork' (pork is a kind of meat).
'say' becomes 'eg' (both can mean for example).
'eating' is an insertion indicator.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
The alternating letters of 'wodges' are 'wde'.
'pork'+'eg'='porkeg'
'porkeg' enclosing 'wde' is 'POWDER KEG'.
Can you help me to learn more?
(Other definitions for powder keg that I've seen before include "potential disaster" , "Potential source of explosion" , "Barrel for holding explosive" , "Potential source of explosive violence?" , "Dangerous situation" .)
