"Hamburger time" is a euphemism used by the band Dethklok for anything to do with actual death. It originated in "Dethhealth", during a meeting with Offdensen to discuss a recent concert where the band was nearly crushed by the decapitated head of the Sphinx of Giza. Nathan expresses his displeasure at the number of times Offdensen uses terms like "die" and "dying", demanding he "use a different word, something like...something that's good". Murderface immediately suggests "hamburger time" as a more upbeat-sounding term, which is agreed upon and adopted by the rest of the band.
