The phrase comes from everyday Spanish spoken at markets and food stalls, where asking a como asks the price of something sold by weight or portion. As a short isolated clip it spread through meme pages, TikTok edits and WhatsApp audio shares, detached from any single stall or seller. Its humour relies on shared recognition rather than a known character or film, which is why creators reuse it for any cheap snack, bargain or craving joke without needing setup or explanation from the listener today.
