Ebisumaru is the comic partner of Goemon in Konami's Mystical Ninja games, known in Japan as the Ganbare Goemon series, a long running action adventure franchise mixing feudal Japan with folklore creatures like the oni. Short character shouts from games like these became popular as soundboard clips because they are instantly readable without any context. This one circulated as a standalone reaction sound, reused far beyond the original adventure by players who wanted a quick folklore themed alert. Its brevity and recognisable single word delivery keep it in rotation for gaming memes.
