Just pour coming back (4)
I believe the answer is:
meet
'just' is the definition.
('meet' can be similar in meaning to 'just')
'pour coming back' is the wordplay.
'pour' becomes 'teem' (I've seen this before).
'coming back' shows that the letters should be reversed in order.
'teem' reversed gives 'MEET'.
(Other definitions for meet that I've seen before include "assembly at hunt" , "Get together socially or for business" , "Confront" , "counter" , "It is proper to encounter" .)
