The phrase 'all rise' is the traditional call made by a bailiff or court officer when a judge enters a United States courtroom, a signal for everyone present to stand out of respect. That real courtroom ritual made the line instantly recognisable in films, television court dramas and news coverage of trials. Short recordings of the call later spread online as a reusable sound effect, clipped for edits where creators stage their own trials, pronounce judgements on friends, or give an entrance an exaggerated sense of ceremony and authority.
