noun: loud, obnoxious exhaust system, most likely on a crappy foreign car, driven by
douchebags. Usually installed improperly thus creating not a respectable sound of a finely-tuned race car, but a loud, droning buzz or series of pops that the owner of said car thinks is truly amazing, sounds awesome and is a true show of horsepower. Uncannily attracts teenybopper girls who think the car is straight out of Fast and Furious or other douchebags with similarly crappy cars and annoying exhaust systems.
