PRO96 takes its name from the raw soundboard title it was uploaded under, and no confirmed source work, character, or release year is attached to it. Clips with code style names like this tend to spread through shares, reposts, and soundboard collections rather than through a single viral scene. Its continued use comes from its flexibility, as a short, self contained clip that editors can drop into very different contexts without needing any background knowledge from the viewer to make the moment land.
