In video games, it's when you collect a bunch of a certain item in order to power yourself up.

1. In videogames, collecting a certain item (usually a currency) in order to power one's character up.

2. In Maple Story, killing monsters for mesos and items to sell.

3. (Although it is quite obscure) In Call Of Duty, when one lures other players to oneself and camps in order to take in a massive amount of kills. Usually some type of SMG or MG is required for this farming.

The act of "growing" relationships via social network like Facebook or Myspace by "planting" a "seed" and watching it grow. Seed is often a random IM that grows into a conversation which leads to a meeting which ends with a hook up.

During sex the man or woman will shit on the stomach of the other partner and spread it flat. Once you do that, you piss all over it as if you were watering crops.

The act of hanging around public toilets and fishing out turds, particulary those produced by people who one finds attractive.

1) The act of sleeping in excess of what is needed, sleeping on an irregular schedule, sleeping through one's own alarm, phone calls, loud noises, or any other attempt to wake the "farmer" up.

2) Missing activities due to chronic fatigue caused by irregular sleeping pattern/laziness.

The act of online gaming for many hours without end. Origination came out of my friends playing Farm Ville and Farm Town on Facebook for hours on end and doing nothing else productive.

Whenever these people are playing ANY game, they can be said they are farming.
