Sound Bomb

When you put an extremely loud video, typically ear rape, on a bluetooth speaker and throw it to someone, usually setting the video to start playing at a point where there's five seconds left until the audio plays. This makes it look like a type of grenade. It's typically used to get a group of people out of the room if they're kind of in your space and business or just to ward someone off. It can even be used to ward off ghosts due to the electromagnetic and vibratory nature of sound. The term "sound bomb" also refers to explosive devices that generate lots of sound like flash bang.
