Gush, disgorge (4)
I believe the answer is:
spew
This clue is a double definition.
'gush' is the first definition.
(I've seen this in another clue)
'disgorge' is the second definition.
(I know that disgorge can be written as spew)
(Other definitions for spew that I've seen before include "bring it up" , "Forcibly eject" , "Erupt, eject" , "Cast out in a stream, vomit" , "issue" .)
