Recadinho pra vc uses informal Brazilian Portuguese spelling, with vc shortening você, a style common in texts and voice notes. Clips like this circulate mainly through WhatsApp groups and soundboards, where a one second spoken line can be replayed out of context for comic effect. Its appeal comes from that familiarity, sounding like a real friend is about to tell you something, which makes it reusable for jokes, call outs and fake announcements across short videos and chats without needing any setup or explanation beforehand.
