Malagasy primate votes in the affirmative (3-3)
I believe the answer is:
aye-aye
I believe this is a double definition.
'malagasy primate' is the first definition.
(primate native to Madagascar)
'votes in the affirmative' is the second definition.
(an 'aye' is an affirmative vote)
(Other definitions for aye-aye that I've seen before include "Nautical 'yes'" , "Rare Madagascan primate" , "A lemur; yessir!" , "Nocturnal primate - seaman's expression of compliance" , "1 across" .)
