Cry — “Sounds like bouncer!” (4)
I believe the answer is:
bawl
'cry' is the definition.
(I know that bawl is a more specific form of cry)
'sounds like bouncer' is the wordplay.
'sounds like' indicates a 'sounds like' (homophone) clue.
'bouncer' becomes 'ball' (something that bounces).
'ball' sounds like 'BAWL'.
(Other definitions for bawl that I've seen before include "wail of discontent" , "What baby does" , "Shout; sounds like dance" , "Shout loudly" , "Supporter of Charles I" .)
