Bico do Corvo by MCH circulates as a short user-uploaded clip on soundboards, where it is credited to MCH and kept in collections of brief reaction sounds. Its exact original recording is not widely documented, so most listeners encounter it through memes, edits and short videos rather than a single well-known show or film. That low-key, community-driven spread suits its length: at under three seconds it is easy to reuse, easy to recognise after a few plays, and easy to drop into a new context without needing much explanation.
