Revved

Revved is the past tense and past participle of the verb rev, meaning to increase the speed of an engine by pressing the accelerator, causing the engine's revolutions per minute (RPM) to rise and the exhaust to emit a higher-pitched sound. The term is most commonly used in automotive contexts and is closely linked to engine performance and sound.

The verb derives from revolution or revolutions per minute; in British English, the noun form revs is commonly used to refer to engine RPM, as in the car has high revs.

Usage: Drivers may rev an engine to warm it up, to signal readiness, or during shifting and acceleration. In everyday speech, revved can describe an engine's state or a person’s energy, as in the crowd got revved up.

In culture and media, revving engines appears in drag racing, car advertisements, films, and music, often used to convey speed, aggression, or excitement. Sound design frequently simulates revving for dramatic effect.

In broader contexts, revved up or revved can describe any mechanism that has been started or accelerated, and as an adjective it can imply heightened intensity, though it is primarily used with engines.
