Quad Damage is best known as a power-up from the Quake series, where it grants massively increased damage and became one of the franchise's most memorable gameplay cues. The phrase and its audio identity spread through arena shooter culture, frag movies, and retro PC gaming compilations. It still gets reused because even people who never played Quake often recognize it as shorthand for a sudden boost, a dangerous advantage, or a brief overpowered state in a game clip.
