Having a Brazilian flavour, perhaps? (5)
I believe the answer is:
nutty
I'm afraid I can't explain this answer.
Can you help me to learn more?
(Other definitions for nutty that I've seen before include "Like cobs, brazils, etc" , "Mentally unhinged (slang)" , "Round the bend?" , "19 [LUNATIC]" , "Crazy - slack?" .)
