Here's a few new words from the the New Oxford American Dictionary that just might help with our financial planning:

Frugalista  person who leads a frugal lifestyle, but stays fashionable and healthy by swapping clothes, buying second-hand, growing own produce, etc.

Hypermiling  Do you keep the tires on your car properly inflated to maximize your gas mileage? Have you removed the roof rack from your vehicle to streamline the car and reduce drag? Do you turn your engine off rather than idle at long stoplights? If you said yes to any of these questions you just might be a “hypermiler.”
