Expel, force out (5)
I believe the answer is:
eject
I believe this is a double definition.
'expel' is the first definition.
(synonyms)
'force out' is the second definition.
(synonyms)
(Other definitions for eject that I've seen before include "Throw out violently" , "Turf out" , "Send out forcibly" , "Throw out forcibly" , "DVD player button" .)
