Tata Werneck is a Brazilian comedian, actress and TV presenter who became widely known through her irreverent comedy work on MTV Brasil. The chant 'xupa, xupa' plays on a crude Portuguese playground taunt, delivered here in her signature exaggerated, manic style. Short reaction clips of her rants and catchphrases circulate widely on Brazilian soundboards and WhatsApp groups, where her over-the-top delivery makes them instant memes. It functions as a Brazilian cousin of the classic mocking laugh, packing pure schadenfreude into a bouncy, unmistakable voice.
