The phrase comes from Chilean internet slang and spread as a short voice note and TikTok sound, where users repost the same few seconds over unrelated videos. In Chile and across Spanish speaking social media, saying la mama de tu mama works as a nonsense comeback, similar to a your mom joke but aimed one generation higher. Its rhythm and repetition made it easy to loop, caption and share in WhatsApp groups, which helped it survive beyond a single trend cycle and become a reusable reaction clip.
