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)"
The sacrifice is a method of revenge and should only be used when all people involved in seeking revenge agree the victim should be sacrificed. When a guy or girl does something to make you mad, then you can sacrifice them. Essentially, you talk the guy or girl into hooking up in their parent's room while their parents are out to a movie or dinner. Then once you're in the parent's bedroom, you handcuff the guy or girl to the bed and start turning then on. The person seeking revenge should keep going down on the guy or girl until they're just about to cum and then get up and walk away, leaving the person hand cuffed to their parent's bed naked and unable to hide. If the victim is a guy, he'll have a mean case of blue balls, and if it's a girl, her parents will have a lovely view of her all wet and wild on their bed. In either case, the person will be unable to finish the job you started on their own while handcuffed, and unable to hide before their parents return home eager to go to bed. Leave the key somewhere out of reach of the person so that their parent's can uncuff them later.
to clarify, here is a detailed example... This guy, let's call him Joe, cheated on my best friend. So, to get back at him I started hitting on him all the time and he eventually invited me over to fool around while his parents were out. I brought hand cuffs and talked him into letting me cuff him to his parent's bed, I convinced him that I'm into hand cuffs and stuff like that. Then I started giving him head and when I could tell he was getting close, I stopped and got up. I told him that I thought he was an ass hole for hurting my friend and waived the key to the cuffs infront of his face and placed it on the coffee table acrossed the room and left the door wide open on my way out of the house. he told his friends the next day that his dad flipped out when his mom and him walked on their son hand cuffed and naked to their bed with a huge boner.
this is called "the sacrifice" because it's similiar to when a tribe ties an animal or person to a pole as a sacrfice to some wild animal or god that will come and eat him later.
