Ok I got inspired from @daxwormzz's headcanon that Wolf and his sons are Ojibwe, it grew on me hehe. Also HC Wolf and most of his family are fluent in the language and he taught Barry and Simon too from a young age. They use it to communicate in order not to be understood, but them being them aka dumb af, they often forget their father understands everything they say. Usually, he is too tired to correct them and let them think however they want to wondering where they possibly took their brains from. I let you search what "wiinuk" means by yourself lol
