The phrase spread online as a short reaction audio, with 'blud' giving it a distinctly British internet slang flavour and Diddy providing the recognisable public figure at the centre of the joke. Loud versions became popular because the extra volume makes the disbelief feel more theatrical in short-form edits, where a sound needs to register immediately. It is now mainly used as a commentary clip rather than a quotation from a film or show, dropped over moments that look absurd, suspicious or hard to explain.
