The 'DUN DUN' meme draws its inspiration from the iconic two-note sound effect used between scenes in the Law & Order television franchise. Created by composer Mike Post, the sound—often described as a 'clanging' or 'thumping' noise—has transcended television to become a universal shorthand for a dramatic plot twist or a shocking discovery. In the world of internet memes, it is used to punctuate moments of sudden realization, awkward confrontations, or minor inconveniences that feel like a federal crime. Whether you're catching a friend in a lie or realizing you've made a terrible mistake, the DUN DUN text adds an immediate layer of theatrical suspense and comedic weight to any situation.
