Flash Mob

Unannounced gatherings of people performing a choreographed dance or other coordinated action in public places.

Also, an 80s rock band.

Or a type of computer graphics effect.

Mob Rules are made to be broken.

But don't worry, we Flash Bomb will take care of you.

Or, you know, just Flashy Tunes will do.

Or maybe you're thinking of a Flash Gordon?

Or Flash Drive, the ultimate party game.
