Little reliable detail is available about who first recorded this version of the line, so its appeal comes mainly from how it circulates online as a short, shareable reaction clip. The familiar sheesh exclamation gives listeners an instant cue that something impressive or surprising has just happened, while the unusual sag whalla ending makes it easy to recognise in a feed full of similar sounds. Creators reuse it because it is brief, easy to place over a single moment, and instantly signals playful disbelief without needing any extra explanation.
