This clip comes from Lyrica, a VTuber known to fans for loud, expressive live reactions during streams. Short scream moments like this one were cut from broadcasts and shared as standalone sounds, with this version labelled as the second Lyrica scream. It spread through soundboards and creator communities where VTuber clips are often reused as reaction audio. Its popularity comes from how recognisable and extreme the reaction is, so editors keep using it for shock, fear and comedy moments online long after the original stream context is gone.
