While the exact original recording behind this clip is not widely documented, the phrase itself is everyday Portuguese for asking people to answer, which makes it instantly recognisable to Portuguese-speaking audiences online. Short voice clips like this travel well on soundboards and in short-form edits because they need no translation to land as a reaction, and they are easy to drop over chat screenshots, memes and skits. Its staying power comes from that simple, relatable situation: everyone has waited for a reply that never came.
