The phrase is Brazilian Portuguese slang built around taca o pau, an expression meaning to go hard or hit it, combined with priquito in a deliberately crude, playful way. Clips like this spread mainly as short WhatsApp voice notes and reposted meme sounds in Brazil, where the humor relies on tone more than literal meaning. Because it is short, loud and instantly recognisable to Portuguese speakers, it survived as a reusable reaction clip for edits, group chats and short videos long after individual reposts.
