The line comes from the 2014 comedy 22 Jump Street, where Channing Tatum as Jenko tries to adopt a fake accent while undercover and introduces himself as Jeff. The scene was clipped and shared heavily on Vine in 2014, where its short length made it perfect for looping edits and remixes. From there it spread to YouTube, Instagram and TikTok as a universal joke for bad disguises and forced introductions. It remains popular because almost everyone recognises the delivery instantly, even without seeing the film.
