This clip is mainly recognized online as a short anime-style wow reaction rather than as a widely documented quote with a clear mainstream source. It spread through meme edits, short-form videos and soundboards where creators use it to signal impressed disbelief in a split second. Its staying power comes from how fast it communicates the feeling: one expressive line can turn an ordinary reveal into a playful reaction beat. It often appears in the same kind of edits as other quick reaction sounds such as bruh.
