Wasting time you don't have on Facebook stalking people, or reading their walls.
Girl: I'm so upset that Justin has a girflriend, now I have no chance.
Guy: How on earth did you figure that out?
Girl: I was reading his wall conversations with one of his friends, you know, back and forth between their two walls so I could get the full converstaion and his friend congratulated him on having a hot girlfriend.
Guy: You were face creeping at home all alone last night?!?! Maybe you should go out...

When someone studies peoples posts on Facebook (Comments, pictures, status updates) to the point to where they know everything about a persons life, without ever talking to that person. A classic Face-creeper is known to know way more about a victim than the victims best friends know about him.
Phil: "Who knows where Kelsey is?"

Sid: "Oh. Kelsey is soo totally bored while grounded for getting a D+ on her math final."

Doug: "What?!... When did you talk to her? I didnt even know you guys talk that much.."

Sid: "Kelsey added me last week on facebook. Did you not see her latest 8 updates?

Doug and Phil: "FACE-CREEPER"
