Machin is a character from Pataclaun, the popular Peruvian sketch comedy series, performed by Carlos Alcantara, widely known as Cachin. The line y tu como te llamas became a familiar catchphrase from the show, and short clips of it later circulated online as a meme sound and WhatsApp audio. Its appeal has lasted because the question is simple, instantly recognisable to Peruvian viewers, and easy to reuse whenever a video needs a funny introduction.
