Means monkey in Portuguese. My Brazilian buddy said it's one of the insults they use down there. I couldn't decide between that or "puseta". You should be able to guess the meaning of that one, though.
There was a video a few years ago when Pride was still around. Right before the second Rampage/Wandy fight. They were interviewing Rampage at his home and he was talking shit about Wandy. He was using macacao and puseta all over the place. Was funny shit. Right up until Wandy split Rampage's face into pieces and left him half dead.
