Nani comes from the Japanese word for what and has been a staple expression of shock in anime for decades. Online, exaggerated versions of the shout were clipped and shared as standalone reactions on meme pages, video edits and soundboards. Its appeal is how clear the emotion is without subtitles, making it easy to reuse across different scenes and jokes. It is now often grouped with other anime staples like the To be Continued JoJo ending for comedic edits and reaction compilations.

The classic anime nani sound effect of a shocked character shouting what in Japanese, used for surprise reveals, plot twists and funny reaction moments.
Nani is a short anime voice clip built around a single shocked exclamation meaning what in Japanese. A male character delivers the word with rising disbelief, stretching the moment as if his brain has stopped working after hearing something impossible. The delivery is loud, dramatic and instantly readable even if you do not speak Japanese. That over the top reaction is why it lands so well as a punchline, turning an ordinary surprise, mistake or plot twist into something that feels huge, absurd and funny for the viewer watching.
