A 2.4-second voice clip of someone delivering the line 'rawr, I'm a dinosaur' in a deliberately childish, goofy tone. It feels funny and endearing rather than frightening, because the attempt at a fierce roar comes across as harmless, awkward and completely unserious, which is exactly why listeners treat it as a cute joke instead of a scare.
