A woman who has passed her fertility window and has become very unattractive to men.
After women hit 35, they are basically a post wall woman. It's like they hit a wall at full speed and their face got all messed up.

Well Wishes written on facebook pages for friends and family's birthdays.

A substitute for Birthday cards.
"Dude,Just wanted to write you birthday wall post, happy birthday you are the bombest!"

Birthday wall posts rules:
1. Short birthday wishes should be posted to the wall, longer birthday wishes should be sent as messages so as to keep the wall space interesting, and avoid irritating the birthday wall-post stalkers.
2. One should read all other birthday wishes before posting a new one so as to avoid repitition, however, in some cases, a simple two-worded "Happy Birthday" can be appropriate. excample: (1)You don't know the person very well. (2)You don't but you're just saying happy birthday cause you're bored. (3)You havn't talked to them in a year or more. (4)You met in Yoville.
3. NEVER write your birthday wish in the form a comment of agreement with someone els's post. ie: Person writes birthday wish and you comment "Yeah".
4. Keep in mind that everyone knows the birthday song so it is not necessary to write it out.
5. Don't post belated birthday wishes. Just pretend you weren't online to see the notification.

The Wall Post Theory states that the probability of someone hooking up with a particular individual is directly correlated to the number of Facebook wall posts made by that individual.

The Text Message and Poke Corollaries state the same for text messages and Facebook pokes. This correlation is even stronger but not as useful due to the lack of publicly available information.
I saw her facebook - he was all over her wall and
I said, "Yo, who was that?" "Oh, he's just a friend"
Don't gimme that, don't ever gimme that
Jus' bust this

You, you got what I need but you say he's just a friend
And you say he's just a friend, oh baby
You, you got what I need but you say he's just a friend
But you say he's just a friend, oh baby
You, you got what I need but you say he's just a friend
But you say he's just a friend

When you are having a conversation with someone over facebook, but your conversation is consisting of only posts on each other's walls. Then randomly after about 3 posts, the other person decides to continue the conversation by adding a comment to your wall-post, instead of creating a new post on their wall, thus giving the illusion of them being more popular when one looks at their wall.
