When a car is very clean in appearance, a monster with power, or both. You normally see these cars in the summer months or in warmer climate states. These vehicles make your jaw drop
Person 1: did you see that sick mustang?
Person 2: yeah, but that camaro was a fuckin boss car!

Get the boss car mug.
An oversized, petrol-guzzling monstrosity of the kind which is particularly to blame for trashing the planet. e.g. Mercedes, Rolls Royce, limo, etc.
I'm going to go smash up that boss car.

If you get run over by a boss car, you can sue the rich git driving it for loads of money.
