Not really a prank but a cool story that I tell. At airsoft once, I brought my bluetooth speaker and BLASTED The Doom 2016 soundtrack and The halo 2 tracks that have eletric gutar. it was in the middle of a war and the refs paused the game for a moment to tell me to turn it off, and ligit everyone on my team and opposite team said "No." so the rest of the day we just shot each other while listening to rip and tear.
