The clip centres on Puniru, the cute slime character whose high-pitched reactions have become popular with anime meme editors. Short, expressive anime sounds travel well because they can be dropped into almost any reaction video without needing context, and this one stands out because the anger sounds playful rather than harsh. It is now used as a quick punctuation mark for frustration, teasing and overreaction, especially in short-form edits where a single second of personality can carry the joke.
