The exact anime source of this short clip is not documented, but the phrase itself is familiar Japanese slang for rallying others, combining a call to go with a sharp attention-grabbing oi. On soundboards and in short-form video, clips like this circulate because they are instantly recognisable as anime energy even to viewers who do not speak Japanese. Creators reuse it as a hype cue at the start of challenges, reveals and comedic run-ups, and its brevity makes it easy to drop into memes without losing pace. That combination of clarity, energy and length keeps it in rotation.
