'Em 20 anos' circulates online as a Portuguese-language voice meme, most often shared as a short WhatsApp audio among Brazilian meme communities. Its exact origin is unclear, but the phrase's deadpan delivery made it a reusable template: creators drop it ahead of jokes about aging, predictions and exaggerated futures, especially in short-form video. Because it needs no translation to set a mood, it keeps resurfacing in reaction edits and ironic montages, surviving as a small, flexible building block of Portuguese internet humor rather than a quote tied to one video.
