This two-second voice clip repeats the blunt catchphrase ain't nobody got time for that in a flat, fed-up delivery. It lands as funny exasperation, the sound of someone shutting down a silly suggestion or extra chore instantly without arguing, explaining, or pretending to consider it for even a moment longer.
