Donkey jackets heading for incinerator in present condition (2,2)
I believe the answer is:
as is
'in present condition' is the definition.
(I've seen this before)
'donkey jackets heading for incinerator' is the wordplay.
'donkey' becomes 'ass' (ass is a term for a donkey).
'jackets' is an insertion indicator.
'heading for' says to take the initial letters.
The first letter of 'incinerator' is 'i'.
'ass' enclosing 'i' is 'AS IS'.
(Other definitions for as is that I've seen before include "With no changes" , "in the present circumstances" , "without change" , "current state" , "not changed" .)
