A short spoken line from Steins;Gate, delivered by a single voice in just under four seconds. It feels playful and slightly absurd, the kind of quick reaction that lands because it is so sudden and specific. The line comes from that series, where its odd phrasing makes it stand out as a memorable in-joke for fans.
