Short greeting clips like this spread mainly through messaging apps and soundboards, where a named hello becomes a reusable joke anyone can drop into a conversation. The Hola Karen Agarayua line works because it is specific enough to feel personal, yet short enough to reuse for any Karen in a chat, video or stream. Spanish language audios travel especially well across Latin American and Spanish meme communities, getting reshared as voice notes, edited into short videos, and saved as a quick reaction for everyday greetings.
