Douche-box

A shit-box car (usually owned by a teenager that just got their licence) that has had needlessly loud, expensive and fast modifications added to it people who drive around in these cars are generally douchebags who think buying a loud ass V8 engine for a used 2008 Toyota will make them look cool and is a good use of their part-time savings (spoiler alert, it's not).

Thomas: what the hell is that loud sound? Is that a sports car?

Dan: no it's just Jared drifting around the school parking lot in his Douche-box.
