Espuma means foam in Spanish and Portuguese, and the phrase Coca Cola espuma spread online as a label for clips of fizzy soda foaming over. The exact first upload is not clear, but the sound circulated through TikTok, meme pages and Russian language soundboards where users transliterated the name as koka kola ekspuma. Its appeal is simple timing: a familiar drink, a quick burst of fizz, and an exaggerated mess that works as a punchline without needing dialogue or context to understand the joke.
