The clip was uploaded by a user on a meme soundboard, with file metadata crediting a Spanish voice-changer site and its helium effect preset, so its exact creator is unknown. 'Onichan' plays on 'oniichan', the Japanese word for big brother, a long-running joke across anime fandoms and Spanish-language meme pages. Low-effort voice-changer audio like this spreads through WhatsApp groups and short-video edits, where the distorted delivery carries the joke. Like other goofy ahh sounds and scream meme clips, it survives as a reusable reaction rather than a reference to any single video.
このサウンドについて
A helium-voiced 'onichan' meme clip made with a voice changer, mixing anime slang and Spanish humor for anime edits, pranks and chat reactions.
This four-second clip squeezes a playful Spanish meme voice line through a helium voice changer, stretching the voice into a squeaky, cartoonish pitch that lands somewhere between an anime catchphrase and a prank call. The word 'onichan' – a riff on the Japanese 'oniichan', meaning big brother – gives it instant anime-meme recognition, while the wobbly high-pitched delivery makes every syllable sound exaggerated and silly. It hits listeners as pure comic chaos: the kind of distorted voice that turns a mundane edit into a joke, a group chat message into a punchline, and a reaction video into something shareable.
