The phrase translates as let the speakers make a boom, and online it is used as shorthand for turning a sound system up until the bass takes over. Short clips like this spread through party, car audio and dance edits, where a spoken hype line works better than a plain sound effect because it tells viewers what is coming next. Its appeal is practical rather than tied to one video, since the thirteen-second cue can open a bass test, a speaker showcase or a transition, and it still works for creators who want a loud build-up without a long intro.
