The clip comes from Re:Zero Starting Life in Another World, the fantasy anime centred on Subaru Natsuki, where the healer Felix Argyle is known for playful, cat-like teasing. A brief ear-biting moment was isolated by fans and shared on soundboards under short, garbled titles, turning a tiny character interaction into a standalone reaction sound. It spread in anime edit communities because it needs no dialogue to be understood, and it remains used for light, affectionate jokes rather than dramatic or aggressive scenes.
