Konnichiwa has been the standard daytime greeting in Japanese for generations, roughly meaning good afternoon, and anime exported it worldwide as the default hello viewers expect to hear. Short voice clips of the word spread through soundboards and video edits because the pronunciation is clear even to non-speakers. It sits alongside other short Japanese anime voice clips like Yamate Kudesai and Tuturu that creators reuse as instant reaction cues. The clip stays popular because two seconds is enough to signal anime style, friendliness and a fresh start.
