Farmheads

People who play the ridiculous, immature game called Farmville, which is popular on Facebook. These people will often tease you for liking your game of choice if it's not Farmville (such as something more entertaining and hardcore, like World of Warcraft).

Farmhead:
"I need to get home and tend to my cows on Farmville like all my fellow Farmheads on Facebook!"

World of Warcraft player:
"Well, I need to get home and kill cows (tauren) in battlegrounds! So shut up, I'll pwn you noob!"
