"I don't really want to be friends with my sister on facebook, but she has a lot of people I know, so I friend farmed her."

"Wow, you two aren't friends on here, but you have almost identical friend lists!"
"She's probably a friend farmer"

"He asked for my myspace link, but he never friended me"
"You just got friend farmed!"

When Jason and Heather got married, the joining of their friend mines created a friend farm for upfriending.
