Thanks to this:
http://www.cracked.com/article_16275_9-most-devastating-insults-from-around-world.html EDIT: Which led me to thinking about insults in languages and cultures in my constructed worlds for stories. Like Traipah. I haven't thought of much for Ah'Koi Bahnis insults... aside from "dwahtaim" as a mildly insulting word for humans, "viihiil" meaning stupid, and "vekii" as "shit." (Da-vekii being plural for shit.)
However... there is a whole bunch of insults in Duenicallo. Their culture is less proper, verbally, than the Ah'Koi Bahnis culture. There are some real doozies in their language. Which can be found
here, if you scroll past the nonsense. (BTW, Dvencoilii is the Duenicallo language.) Though that page only scrapes the surface of interesting Dvencoilii insults.
