The sound comes from the trailer music for Christopher Nolan's Inception, released in 2010, where Hans Zimmer's deep brass motif became shorthand for blockbuster tension. Trailer editors copied the effect for years, and online creators then turned it into a joke, using the same ominous blast to hype up small, ordinary moments. Its spread was driven by reaction videos, edits and soundboards, where a three-second blast could instantly signal that something huge, or hilariously overhyped, was about to happen.
