Kyojuro Rengoku is the Flame Hashira in Demon Slayer: Kimetsu no Yaiba, and his booming love of food became one of his most recognisable traits in the anime. Fans turned his enthusiastic tasty exclamation into a short reaction sound that travels well beyond anime edits, because the meaning is clear even without subtitles or context. It is now commonly used in food videos, memes and short-form edits, where a single cheerful word can turn an everyday meal into a small celebration.
