Screened out

When you have worked online for ages staring at the screen or spent the day surfing.

I have been working online all day long, my eyes kill...I am screened out

Facedout

When you message a girl, or write on her Facebook wall and she doesn't respond, yet she responds to others promptly.

"What happened to that Jennifer girl, did you add her?"
"Yeah I added her and sent a message asking her what's up too"
"What happened?"
"I got facedout man"
"Ah, bummer bro"

No stalk

Phrase used before one inadvertently says something that sounds stalkerish on Facebook.

Carter: "No stalk but I noticed you changed your quotes on your profile. I love Hunter S Thompson too!"

Jane: Okaaay.
