So, its July 4, or whatever. Instead of having a nice, choreographed fireworks display, you take all of the fireworks and throw them into a raging bonfire all at once, and start running. This is the Devil's Ballsack.
Running through the forest dodging flaming balls, explosions, jets of fire, etc., it would be appropriate to yell "Devil's Ballsack! Fuck Yeah!" to similarly running friends.
