South Park redefines what it means to be a "fag"

Noise pollution is a serious problem all around the world. For years, we have worked on making newer vehicles more efficient and less noisy. With better batteries for hybrids and plug-in electric vehicles, we could make it possible for vehicles to almost noise-free. New South Wales, in Australia, already seems to have rules regarding loud vehicles and we could see if we need similar legislation where we don't have it.

By the way, here's the definition as quoted on the English Wikipedia article as I mentioned in the title:

"Fag (făg) n. 1. An extremely annoying, inconsiderate person most commonly associated with Harley riders. 2. A person who owns or frequently rides a Harley."

It would be interesting to know the motivation behind this episode of South Park.
