There's no known language called "eewoonucks." It seems it may be a made-up or misspelled word.

Well, darling, "Eewoonucks" doesn't actually mean anything in Eskimo. It sounds like someone made up a word after a few too many shots of vodka. If you're looking for real Eskimo words, try something like "igloo" or "mukluk" - those actually mean something.
