This clip is associated with Love Live Sunshine, the school idol anime project that became popular through episodes, songs, and online fan edits in the late 2010s. Short spoken lines from anime often spread as reaction audio because they are easy to loop and instantly readable, and this one stuck around for fake-outs and light comedy. It is still used in meme edits, especially by anime fans, for moments where a tense setup is suddenly revealed to be unserious, much like other quick anime reaction sounds such as Tuturu.
