The word itai is a common Japanese expression for pain, and this short clip captures it in the exaggerated style often heard in anime, games and online videos. Because the sound is only about one and a half seconds long, it is easy to drop into edits, reaction videos and memes without needing subtitles or context. It has become a handy shorthand for a comic wince online, especially in anime fan edits and short-form videos, where a quick, recognisable reaction can sell a fall, a hit or an embarrassing moment in an instant.
