This clip comes from James May, best known as a presenter on British motoring television, and it spread online because his delivery turns one ordinary word into a memorable reaction. Short uploads and reposts helped the sound circulate as a standalone meme, especially in absurd edits and food jokes. Its staying power comes from the contrast between the plain word and the very specific way he says it. Creators often use it in the same broad reaction-sound space as a bruh meme.
