look up any word, like thot:
Adjective added to make something sound new, trendy, or better when it's really just the same warmed-over crap.

Way overused these days, to the point of being corny.

Example: Smart Cars, Smart Timer, Smart investing, Smart menu
Marketing: Look, it's the new Smart Car.
Really: An engine on a cheap plastic chassis selling for 18K. More cheaply made than the 9K Chevrolet Aveo.

Marketing: This new Smart timer turns can turn your lights on when dark.
Really: Nothing more than a fancy light-sensor. They've been around for 50 years.

Marketing: ING direct is a smart way to invest your money.
Really: Just a bank CD. No smarter than any other bank CD. Only called "Smart" to mask the hidden fees.

Marketing: Behold the new Dunkin' Donuts Smart Menu.
Really: Formerly known as the low-fat menu. Now it's somehow "smart."
