Ambrosia has sold Devon custard in Britain for decades, and its television adverts have long played on a relaxed West Country image, with creamy desserts linked to Devon farms and countryside. The oooh arrr line borrows the stereotypical farmer's expression of approval familiar across British comedy, making it instantly understood even by viewers who never saw the original advert. Online the clip was lifted to soundboards as a standalone reaction, shared for harvest jokes, rural memes and food videos where a slow, satisfied West Country response says more than a full sentence.
