Facebook Blues 

Facebook blues occurs after writing on someones wall, note, or status, and they don't respond. You wait and wait for a response constantly checking your Facebook to see if they have done so.

After the first day of hourly checking your facebook, you begin to facestalk them. This includes checking to see if they have commented on someone elses wall, status, or photos. As a last act of desperation, you send them a private message repeating the original post.

Your sadness resonates throughout Facebook until they respond, at which point you've gotten rid of the Facebook Blues.
