Short VTuber reaction clips like this one are often clipped from streams and shared on soundboards so fans can reuse a favourite moment without searching through long broadcasts. The word itai, meaning painful in Japanese, gives the sound an instantly recognisable emotional cue, which helps it travel across language barriers in meme edits and livestream reactions. Because it is brief and expressive, creators keep returning to it for quick comic punctuation in gaming videos, reaction compilations, and VTuber fan edits, where a single pained sound can replace a longer explanation.
