Anyohaseyo is a common phonetic spelling of annyeonghaseyo, the standard polite Korean greeting used when meeting someone or starting a conversation. On soundboards and in short-form video, the word is often shared as a standalone greeting clip rather than as a quote from a particular show or film. Its appeal comes from how recognisable it is to viewers interested in Korean language, music and online culture, even when they do not speak Korean. Creators reuse it as a quick, friendly opener that signals a Korean theme without needing subtitles or a longer introduction.
