Farmville

Put it like this - You have been given the gift of a human life. You exist as the most civilized and intelligent species known to man. You have the ability to conquer world wonders, discover breathtaking history and knowledge to amaze the world, secure a job with a 6 - figure salary, and you even have the ability to travel space if you work hard enough.

... But instead, you sit at your computer, harvesting virtual crops on a non-existent farm.

Game on Facebook where you do the following:

You buy, you sow, you reap, you sell, you buy, you sow, you reap, you sell, you buy, you sow, you reap, you sell, you buy, you sow, you reap, you sell etc.

A facebook game that people who aren't good at real games play.

A game on Facebook in which after 24 hours of playing, you're a loser

A town in S.central Virginia, home to Longwood University, much maligned as a small town, and for that stupid facebook game. Commonly mentioned as "where the hell is Farmville?" and "Farmville, come early, we close at 5" and the town really does pretty much shut down at 5 o'clock.

A facebook application that constantly needs to remind people about Person A's lonely gray kitten.

A really addictive Facebook application where the user has a virtual avatar who is a farmer. Players earn coins by growing different types of crops/trees and owning animals. As you earn more money and getting more experience from growing crops etc. you move up levels, unlocking other items.
You can also add other friends playing the games as 'neighbours'.
