Told them "outtie 5000," uh
Outtie 5000 is slang for goodbye/peace out.
The origin of the phrase, defined on Urban Dictionary, is as follows:
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 someone hit the gas instead of the brakes.
Another example of the phrase being used can be seen here in the tv show The Wire.
