Deathgasm
When you are so submitted to heavy metal that every once and a while when you listen to it you have a accidental orgasm
Example:
Metal fan 1: "Dude this metal music is sick"
Metal fan 2: "I know I think I just had a deathgasm"
Metal fan 1: "Dude this metal music is sick"
Metal fan 2: "I know I think I just had a deathgasm"
