The sound comes from Wotakoi: Love is Hard for Otaku, the romantic comedy anime about adult otaku coworkers, where Narumi Momose is known for flustered, expressive reactions. Short clips of her scream were lifted from episodes and shared on soundboards and in anime edit communities, where the brief length made it easy to reuse. It sits alongside other anime voice staples like the ara ara line and horror effects like the FNAF jumpscare scream, but stands out for being purely comedic panic rather than flirtation or fear.
