Igor Guimarães is a Brazilian stand up comedian known for his offbeat delivery and characters in live shows and online videos. VTNC is the shortened form of a very common Portuguese swear phrase, widely understood in Brazil as a blunt, joking insult between friends. Clips of his laugh circulated as WhatsApp audios and short meme sounds, where the short length makes it easy to forward and reuse. It sits alongside other Brazilian laugh audios like the risadinha de ladrão in soundboards and chat groups, and remains popular because the laugh alone signals the joke before the swear arrives.
