In my Caves of Qud mod, I added toki-pona-speaking bird-beasts who call themselves "wasoweli"; I figured as 'native speakers' they're entitled to a portmanteau noun for themselves, and that's the only intentional artistic liberty I took with the language.
First used as the name for a species in a mod for Caves of Qud created by akesi kon Nalasuni. Later appeared in ku as exclusively part of a translation for "penguin".
