When someone browses the Facebook photos of his/her "friends" because he/she's bored and finds them doing fun things. As a result, with each click or wall scroll he/she becomes increasingly convinced that he/she should be doing those things with those people, and he/she forgets that he/she is not an important part of any of their lives. After realizing the former statement, the stalker becomes depressed.

Virginia Tech's 'People Finder' on the VT homepage. The perfecttool for finding out the full name, department, email address, and possibly phone number and address of that special someone, before he or she even knows you exist.

I was gonna talk to her today after class, but then I decided to just look her up on Hokie Stalker.
