The sound is tied to Re:Zero, where Felix Argyle and Subaru Natsuki have a playful, teasing dynamic that fans often clip for short reaction edits. At just over a second long, the ear-bite moment travelled as a bite-sized anime sound on soundboards and in fan videos, where its sudden, light-hearted tone made it easy to reuse without needing context. It remains popular because the interaction is instantly recognisable to Re:Zero viewers and still reads as a joke to everyone else.
