Snipe eventually stuffed with grouse (5)
I believe the answer is:
peeve
'grouse' is the definition.
(I've seen this before)
'snipe eventually stuffed with' is the wordplay.
'with' indicates a hidden word.
'PEEVE' can be found hidden inside 'snipe eventually stuffed'.
(Other definitions for peeve that I've seen before include "upset" , "Get annoyed" , "cause irritation" , "bug" , "Cause annoyance" .)
