In Japanese, kora is a familiar interjection used to get someone's attention, often when telling them to stop or pay attention, and it is commonly heard in everyday speech as well as in anime and manga dialogue. Because the word is short and instantly recognisable in tone, even to people who do not understand Japanese, it has circulated online as a compact reaction clip for edits, memes and streams. Its lasting appeal comes from that clear scolding energy, which needs no translation to land in a joke.
