The exact origin of this Zzz clip is unknown, as it comes from a user uploaded soundboard with no artist or source metadata, but cartoon Zzz snore effects have been a staple of animation and comedy editing for decades. Sleeping Z sounds became popular shorthand in memes and gaming fail compilations, where editors use them to signal that a moment is boring or overlong. The format stayed popular because it needs no translation and lands in under two seconds, making it ideal for short form video.
