"Frink" is something lemurs are known to say. Strangely enough, this particular word of lemur language completely eludes human comprehension. "Frink" has more varied and diverse meanings and pronunciations than even "Meow." And anyone who has ever owned a cat can tell you how varied that is. Unfortunately, since we don't know how to pronounce this word, we can't really tell whether a lemur is saying it or not, so there may actually be only one pronunciation and one meaning, and the rest might all be in our imagination.
