Also known a fart cannon, a fart can is a resonator attached to the exhaust pipe of a car (typically found on older,
grocery-getter hatchbacks) intended to give a high performance
exhaust note. However, the sound is almost always best described as a loud, annoying fart (MmmmmmBAAAAAAAAAAMMMMMMMMM, repeated with use of the throttle). Also, the exhaust does nothing for performance. The usual person who buys such a useless item is a ricer (synonymous with idiot). You will never, EVER see these on the car of a tuner or a true
car enthusiast, as the money that would have been used to buy a fart can, would instead be set aside for actual performance modifications, as per the former and the latter, or set towards a better car, as per the latter
Ricer:
Checkit my sweet exhaust, yo! Sound sooo sweet!
Intelligent person: That's just a fart can. All it is, is annoying.
Ricer: Shut up, man! I know more about deez cars and what to do wid 'em than you could dream, yo!
Intelligent person: You are a
waste of oxygen. please go find a fire and die in it.
