Little reliable information is published about where Mokachan was first recorded, so its history is mostly told through how it travels online as a short soundboard clip. The Spanish phrase entrevista caballo attached to existing listings hints at the joke context that helped listeners remember it, even when the original video is not shared alongside it. It sits naturally alongside other short anime voice reactions like anime ahh, and it keeps being reused because the name is distinctive, the clip is brief, and the delivery works without explanation in memes, edits, and reaction posts.
