Vic Mignogna made a joke during a convention. Basically there was a loud room next to where they were, and Vic said "It sounds like a holocaust in there."

Not THE holocaust mind you, but A holocaust. Keep in mind while holocaust can refer to the historic event, the word itself isn't exclusive to that definition and can mean "estruction or slaughter on a mass scale, especially caused by fire or nuclear war." hence terms like "Atomic Holocaust"
