I recall that in my birth community, where no blacks resided, folks commonly calledc young devious kids pikininis or buggers. I dont believe there was offense intended - but things have changed and people now know better. There was also a word for brazil nuts, using the "n" word that is no longer used. Local lobster fishermen used to call their smooth black steel trap haulers the "n" head- thankfully, the term is never heard any more.

Below are some local First Nations terms, which may differ from those used in the USA.
