'lively' is the definition.
(thesaurus)

'operatic prince feeding you in paris' is the wordplay.
'operatic prince' becomes 'igor' (subject of Borodin opera).
'feeding' means one lot of letters goes inside another.
'you in paris' becomes 'vous' (I can't justify this - if you can you should give a lot more credence to this answer).
'igor' put into 'vous' is 'VIGOROUS'.
