The meme comes from a prank call style video that spread widely on Vine in the mid-2010s, helped by the delivery of internet personality Welven Da Great. It quickly escaped Vine and became a broader reaction sound on YouTube, Twitter and short meme edits. Its staying power comes from how fast the setup pays off: viewers instantly understand the bait-and-switch. It is still used when creators want an old-school viral joke that lands in just a few seconds.
