The phrase comes from casual Brazilian Portuguese slang, where vcs is a common texting shortening of voces and muito ruim means very bad. The clip circulates online as a short reaction sound rather than a known quote from a film or show, shared in gaming chats, group messages and meme edits. Its appeal is the imperfect grammar and annoyed delivery, which make it feel like a real voice note from a frustrated friend. That familiarity keeps it in use for friendly roasting long after many longer memes fade.
