a sexual act in which your girlfriend(with braces) is giving you head, you must then take a strong rope and tie her feet to a high powered ceiling fan, upon which her braces will rip your pubes out.

Any import/domestic vehicle fitted with exhaust modifications designed to make it sound more powerful. The net result is generally a car that sounds rediculous, and has no more power than what the driver believes in his own mind.
