Kasane Teto debuted in 2008 as a fake Vocaloid announcement for April Fools Day before becoming a real UTAU voicebank, later gaining a Synthesizer V release and a huge fan following. Short unexpected voice clips of her spread widely through memes, fan edits and soundboards, where her drill shaped twin tails and chimera persona are instantly recognisable. This cursing clip has no confirmed official source, so its popularity comes from fans sharing the out of character moment online as a quick reaction sound.
