The exact film this line comes from is not widely documented, but the clip has circulated as a meme sound on user-generated soundboards, where it is tagged for comedy rather than cinema. Its appeal comes from the deadpan British stereotype: polite, unimpressed and impossible to sway. Short quote clips like this travel well because they work as instant reactions, and this one has been saved, liked and replayed by meme makers who need a quick verbal shield against persuasion, hype and over-the-top salesmanship, in the same spirit as a fail sound meme or the bruh meme.
