One who uses great force to let out extreme waves of gaseous, toxic odours and does so intentionally. One who not only profusely and deliberately expels all nasty smelling gases from body but does so with pride.
A large muffler that creates a farting noise when added to the exhaust system of a four cylinder car. Generally having a large, chrome tip of about 4" in diameter or larger. These mufflers remove backpressure from the exhaust while also reducing low end torque in most engines, this occasionally makes cars slower than stock off the line and not much faster anywhere else.
