From the Urban Dictionary:
An adjective desribing one or more people who intend on leaving a particular place. Audi’s model 5000 sedan was plagued with a problem charcterized by unintended acceleration, in which drivers’ complained that the vehicle lurched forward when their foot was on the brake pedal. In reality, it turned out that the acclerator and brake pedals were unusually close together. This is why Audi 5000 is associated with leaving quickly, because that is what this vehicle did when some old fartknocker hit the gas instead of the brakes.
"I’m Audi 5000". or "I’m Audi".
