The Blue Oyster Bar is a recurring fictional location in the Police Academy film series, a flamboyant gay bar that straight-laced cadets and officers repeatedly wander into by mistake. The joke relies on the contrast between their stiff, macho behaviour and the bar's uninhibited atmosphere, and the accompanying disco music became shorthand for that gag. Clips of the entrances circulated online as reaction and meme material, and creators now reuse the sound to signal a mistaken entrance, a camp reveal, or a sudden change of tone.
