FPA

Friend Point Average. An average Facebook users use to figure out how many friends they actually talk to on Facebook. Divide number of friends you've talked to in the past year by total friends to find your FPA. You can get your FPA up in multiple ways, the most obvious way is by being be more social but if you can't do that you can delete some of your friends you don't speak to in order to bring your average up.

200 (total friends) / 40 (friends you've talked to in the past year either in a wall post, message or fb chat) = FPA of 5
