Uruha Rushia debuted in 2019 as part of Hololive Fantasy, the third generation of the Japanese VTuber agency Hololive Production. Short moments from her streams were widely clipped and shared by fans, and this boing boing line became a favourite for its exaggerated cuteness. Unlike a generic boing boing cartoon effect, the joke here is Rushia herself delivering it in character. The clip spread through VTuber compilations, anime edits and soundboards, and it remains popular because it captures her playful stream persona in under three seconds.
