With no clear original show, film or creator attached to it, this clip has circulated mainly as a short user-generated soundboard sound, where its value comes from how instantly it reads rather than from a famous source. At just over a second long it fits neatly into reaction videos, memes and short-form edits, where a single dismissive bleh can replace a whole line of dialogue. Its popularity rests on that simplicity: it is easy to drop in, easy to recognise, and it keeps working in new contexts because the attitude never needs explaining.
