At the climax of a German or Austrian death/black metal concert, this is the act in which the headlining band torches the entire front row of spectators with a flamethrower. These are the steps:
1.) Lead vocalist lets out a blood scream 'Sacrifice!' (The front row goes crazy, they are ready to meet Satan).
2.) He burns the front row alive with a flamethrower
3.) They continue the show
Vocalist: "The Sacrifice!"
Fan: "Yes dude! I'm so pumped to get fuckin killed! Cannibal Corpse kills without mercy!"
Vocalist: "AHHHHHHHHHHHH (shooting flames)"
