Place it at the very end of a failed play or rule-breaking moment, after the Metal Gear Alert Sound has flagged the trouble. Follow it with the Mortal Kombat Fatality sound to close the joke, or use the DJ Airhorn Sound Effect first if the ban is meant as a celebration.
About this sound
This is a one-and-a-half-second spoken clip delivering the blunt line “you are banned” in a flat, matter-of-fact voice. It feels like an instant shutdown, abrupt and deliberately cold, which makes the joke land as pure fake authority. It comes from TeamSpeak-style voice chat and multiplayer server culture, where the phrase signals a kick, a mute, or an overconfident moderator.
