A farm is a place usually in the country side or out where its open. At a farm they raise caddle such as pigs and cows. They also grow crops such as wheat. Theh take care of chickens so they will lay yummy eggs for us. They milk the cows also. Some farms have horses and sheeps. Sheeps are usually used for wool so that we can have clothing.
On Pimd, a farm is usually someone who you hit 5 or more times in 24hours. This player can be active or inactive. Here is a link to a list of inactive farms.
Sorry Mr.Technicalities xD its a joke. Like all the information needed to be right. Surprised you didn't correct they because I know I spelt it wrong xD
They asked "What is farm?" therefore I helped by giving them the definition of a farm. If however the question was changed to "What is farming?" since this is a PIMD forum I would go on to explain the basics of farming since I farm people and hit BL. Now that I've made that clear I must also note I just helped by fixing their term usage by giving them the correct term to use :3 therefore I was about 15% helpful xD and 85% totally joking around.
