The sound is listed on soundboards under the name So What and credited to Joseph Anderson, but no wider film, television, or viral origin is clearly documented for this particular recording. That has not stopped it spreading as a reusable reaction clip, because the two-word phrase is instantly understood without context.

Its staying power comes from that simplicity: almost any exaggerated complaint can be answered with the same unbothered reply.
