friend surfing 

using a friend (or stranger's) myspace page to check out their attractive or interesting friends, then their friends, and their friends and so on.

I spent most of the afternoon friend surfing on myspace.

Friend surfing 

Killing time by clicking through unknown friend's of your known friends on Facebook. Usually followed by five to ten minutes of friend surfing through complete strangers.

Damn, Toby knows some strange people. (click) This chick is hot, how did he meet her I wonder? (click) Look at this fucking hipster! Too bad Facebook blocks their info...

Friend surfing!!

Surfing your friend's friend lists on Facebook to 'pick up friends'

He is such a loser in the real social world, but has the longest friends list on facebook thanks to 'friend-surfing' - mostly with fake pictures of himself.
