The phrase is everyday Brazilian Portuguese, with vc shortened from você in informal writing, which helps explain its popularity in chat and soundboard culture. Short reaction audios like this spread through group messages, reposts and meme edits rather than a single credited release, so the original speaker and recording are not widely documented. Its humour comes from flipping the expected scare, making the other person the real threat. That simple twist keeps it reusable across gaming clips, fandom edits and everyday conversations online.
