The clip is linked to Pepita, the Brazilian singer and performer whose voice messages and catchphrases circulate widely in WhatsApp audios and meme pages. Boa tarde pra vcs is Portuguese for good afternoon to you all, using the shortened internet spelling of vocês. The sound spread as a reusable greeting rather than a scene from a film or show, shared between friends and added to edits where a cheerful entrance is needed. Its popularity comes from that mix of warmth, slang and timing, which still fits daily Brazilian online humour.
