Llego diciembre, also written llegó diciembre, is a Spanish-language seasonal meme that resurfaces every late November and early December. The phrase simply means December has arrived, and online creators treat the shouted clip as a starting signal for Navidad content. It circulates in short videos, WhatsApp audios and meme edits paired with trees, lights, gifts and family meals. Its popularity renews yearly because the joke is tied to a date everyone shares, making the same audio feel timely again each holiday season without needing context.
