Expire; leak (3,3)
I believe the answer is:
run out
I believe this is a double definition.
'expire' is the first definition.
(I know that expire can be written as run out)
'leak' is the second definition.
(I've seen this before)
(Other definitions for run out that I've seen before include "Cricketing dismissal -- become exhausted (3-3;3,3)" , "Come to an end" , "Dismiss (a batsman)" , "leak" , "Dismissed (at cricket)" .)
