Buenas tardes is a standard Spanish greeting used throughout the Spanish-speaking world in the afternoon and early evening, so the phrase is instantly recognisable even to listeners who do not speak Spanish fluently. Short greeting clips like this one circulate widely as reaction sounds because they are easy to understand, easy to place and work without subtitles. This particular version is kept very short, which suits quick memes, stream alerts and chat replies where a longer greeting would slow the joke down.
