Referral for referral. Usually for Myspace auto-adder users, or for people who use sites like FriendBlastr.
You swap referral codes with another person, and you sign up with each other's referral links so the other person gets extra points. This helps them achieve more VIP days on that site (which means their picture and a link to add them appears on the front page of the site.)

CathyCatastrophe: "heere's miine; -insert link here- kthxbye bbycakes!"
