'venom' is the definition.
(thesaurus)

'bound to stuff a bunny' is the wordplay.
'bound' becomes 'rim' (both can mean a limit or boundary).
'to stuff' indicates putting letters inside.
'bunny' becomes 'cony' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'a'+'cony'='acony'
'rim' placed into 'acony' is 'ACRIMONY'.
