WD-40 was first developed in 1953 in San Diego as a water-displacing spray, and its short advertising jingles became familiar through decades of TV and radio commercials. Playing music backwards has a longer online history, from hidden message parodies to edited logo and blooper videos shared on YouTube. This reversed version takes that recognisable tune and flips it, which is why it circulates on meme soundboards as a quick audio joke rather than a straight commercial clip.
