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.
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...
